Summary of Changes xxviii MRS V3.
Chapter 1. APPN This chapter describes APPN and includes the following sections: v “What is APPN?” v “What APPN Functions Are Implemented on the Router?” on page 3 v “APPN Network Node Optional Features” on page 6 v “Supported DLCs” on page 25 v “Router Configuration Process” on page 25 v “APPN Configuration Notes” on page 49 What is APPN? Advanced Peer-to-Peer networking (APPN) extends the SNA architecture by enabling Type 2.1 (T2.
APPN v A control point (CP), which manages the node’s resources v Resources owned by APPN end nodes and LEN end nodes that use the services of the network node APPN network nodes also: v Exchange information about the topology of the network. This information is exchanged each time network nodes establish a connection or when there is a change in the topology of the network (such as when a network node is deactivated, brought on line, or when a link is congested or fails).
APPN LEN Nodes A LEN node is a T2.1 node without APPN extensions. A LEN node can establish peer connections with other LEN nodes, APPN end nodes, and APPN network nodes, as long as all of the required destination LUs are registered with the LEN node. A LEN node can also serve as a gateway between an APPN network and a SNA subarea network.
APPN Table 1.
APPN v X.25 SVC links v PPP links running over ISDN, V.25bis, or V.34 v Frame relay links running over ISDN v ATM SVC. 3. When the router activates a TG to an adjacent node, it negotiates with that node the maximum message size that can be sent across the TG. If a BIND message is larger than the negotiated message size, the router segments the BIND. Segmentation only occurs if the adjacent node is capable of reassembling the BIND. The router supports BIND reassembly. 4.
APPN APPN Network Node Optional Features In addition to the base APPN Architecture functions, the router also implements the following option set towers and new functions: 087 Garbage Collection Enhancements 1002 Adjacent Link Station name 1007 Parallel TGs 1012 LU name = CP name 1016 Extended Border Node 1061 Prerequisites for SS Extensions for NNS Support 1063 SS Extensions NNS Support 1067 Dependent LU Requester 1071 Generalized ODAI Usage 1101 Preloaded Directory Cache 1107 Central
APPN Protocol (RTP) is used by the endpoints of the HPR connection. HPR intermediate nodes have no session or RTP connection awareness. This new transport layer features: v Selective retransmission error recovery procedure v Segmentation and reassembly v Adaptive Rate-Based (ARB) flow and congestion control mechanism that meters data onto a route that allows efficient utilization of network resources while minimizing congestion.
APPN parameter) must be used. The ISR traffic uses LLC Type 2 LAN frames. The HPR traffic is handled in similar fashion to LLC Type 1 LAN frames and must have a different SAP address. The default SAP address for HPR traffic is X'C8'. If X'C8' has already been used by another protocol on a port, the default must be overridden. Note: There is only one APPN link station even though APPN ISR and HPR traffic use different SAP addresses.
APPN v Layer 3 protocol ID = X'7085' SNA APPN/HPR (NLP) v Enterprise Extender Support for HPR over IP Refer to Table 2 on page 25 for a list of DLCs that support HPR. Note: HPR is not supported over SDLC, X.25, or DLSw ports. Dependent LU Requester (DLUR) The DLUR option extends the support of T2.0 or T2.1 devices containing dependent LUs to APPN nodes. The DLUR function on an APPN network node or an APPN end node works in conjunction with a dependent LU server (DLUS) in a mixed APPN/subarea network.
APPN – Uninterrupted LU-LU sessions, if the supporting DLUS (SSCP) fails – SLU init, PLU init, and Third-party init Restrictions The DLUR option, as implemented on the router network node, has the following functional restrictions: v Only secondary LUs (SLUs) can be supported by the DLUR function. An LU supported by DLUR cannot function as a primary LU (PLU). Therefore, the downstream physical unit (DSPU) should be configured as secondary.

APPN Note: TGs for end nodes are not contained in the network topology database, but are contained in the node’s local topology database. TDUs do not flow through the network when a connection is established through a Connection Network or when an end node is made a member of a Connection Network.
APPN A BrNN accomplishes: v Reduction of the number of network nodes in a large APPN network. v Hidden branch office topology from the WAN. v Direct, peer-to-peer communication between defined branches connected to the same connection network. v Reduces CP-CP session traffic on the WAN link. The following are limitations of Branch Extender: v Network nodes are allowed to connect only over links that a BrNN defines as uplinks. v Only end nodes or cascaded BrNNs may be attached to a BrNN downlink.
APPN Network Topology Example Figure 1 shows many of the connectivity options provided by the BN function. In general, you can get from any network to any other network except that NetF can only reach network NetE and NetE is the only network that can reach NetF. Figure 1. Extended Border Node Connectivity Note: Solid lines represent intersubnetwork TGs. In this figure: v Netid subnetwork NetA has been divided into topology subnetworks.
APPN v Both ends of an inter-network link must be BNs, unless one of the networks is a peripheral network. In this case, the peripheral network may use a conventional non-BN network node to connect to the BN in the adjoining network. This is shown where peripheral network NetC connects to NetB with NNc. v Any LU in networks NetA, NetB, NetC, NetD, or NetE can get to any other LU in any of those networks. Both NetC and NetE are connected using conventional non-BN network nodes.
APPN With the branch extender in place the backbone network’s view of the branch extender is as a giant end node with all the downstream LUs being owned by this giant end node. The backbone has no knowledge of the topology downstream from the branch extender, thus reducing the overhead of topology exchanges.
APPN focal point is designated by its entry points, which initiate communication with the focal point, the focal point is an implicit focal point. The focal point for the router can be either an explicit or implicit focal point. Routers configured as branch extender nodes have additional flexibility. As with conventional network nodes, the focal point can directly establish an explicit relationship with the branch extender node.
APPN CP-MSU Control point management services unit. This message unit is generated by CPMS and contains alert information forwarded by the router entry point. CPMS passes CP-MSU message units to MDS. MDS-MU Multiple-domain support message unit. This message unit is generated by MDS. It encapsulates the CP-MSU for transport between nodes.
APPN The interval between attempts is doubled each time an attempt fails until a maximum interval of one day is reached. From that point on, the attempt is performed daily. Note: If an explicit focal point initiates a management session with a device, it will cause a session with an implicit focal point to terminate.

APPN | | | A pool is a logical group of LUs. These LUs can be from different PUs or the same PU, different Host or same Host, etc. When a client specifies a specific pool name, any LU from the pool may be selected. | | | | There is always at least one implicit workstation pool. This pool is referred to as the global default pool. The name of this Pool is defined via the TN3270E config> set command. LUs must be added to this pool via the TN3270E config> add lu or TN3270E config> add implicit-pool command.
APPN | | | | A mixture of Pool and LU types(Workstation or Printer) can be added to a particular map. The resource selected will be based on the type of connection request. The order in which the resources are defined in the map will be the order in which it is chosen for a particular connection request. | How LUs are Chosen For Client Connections | | | | | | When IP Address to LU Name Mapping is enabled, client IP Address to LU Name Mappings take priority over everything else.
APPN | | | | | in conjunction with the APPN DLUS/DLUR function. The APPN DLUS/DLUR solution allows the node to appear to VTAM as multiple PU devices, each supporting up to 253 dependent LUs. A node wishing to provide TN3270E Server services over a subarea connection for more than 253 clients simultaneously must also appear as multiple PUs to an attached host.
APPN Enterprise Extender Support for HPR over IP Enterprise Extender support for HPR over IP allows HPR/APPN applications to run over an IP backbone network and still take advantage of APPN Class of Service. HPR over IP encapsulates HPR data into a UDP/IP packet for delivery over the IP network. Supported DLCs Table 2 shows the DLC ports supported by the device over APPN: Table 2.
APPN Configuration Changes That Require the APPN Function to Restart v v v v v Network ID of the network node Control point name of the network node XID number (of network node) for subarea connection Adjacent node type (of link station) Change of node function (EBN, BN, NN) v Any parameters under the following options: – High-Performance Routing (HPR) at the node level – Dependent LU Requester (DLUR) at the node level – Connection network – Class of service – Node tuning – Node management – – – – – |
APPN Minimum Configuration This group of APPN configuration steps: v Allows the network node to accept any request it receives from another node to establish a connection. v Restricts the network node from initiating connections with other nodes. If you choose the minimum configuration steps, adjacent nodes must define connections to the router network node to ensure connectivity.
APPN Notes: 1. APPN routing must be defined and enabled on the specific ports you configure the router network node to use. 2. Bridging and DLSw must still be enabled on the specific adapter ports you desire the device network node to use. Initiate Connections Configuration This group of APPN configuration steps: v Allows the network node to accept any request it receives from another node to establish a connection.
APPN 5. 6. 7. 8. 9. Note: Link stations do not have to be defined on every port, only those over which you want to initiate connections to adjacent nodes. Enable the APPN network node. Configure the following parameters for the APPN network node: v Network ID v Control point name Define the XID number for subarea connections parameter for the APPN network node (optional).
APPN v Enable DLSw on the node. v Define the DLSw ports with the following parameter: – Define a locally administered MAC address for DLSw – Disable the Service any node parameter 4. Enable APPN routing on the port. 5. Define APPN link stations on the selected DLC ports for the adjacent nodes: v that may initiate a connection to this network node. v which you desire this router network node to initiate a connection.
APPN have defined the adjacent link station to be a network node on one of the earlier configuration prompts. Answer no if you want the router to appear as a network node on this link. A network node is for links to end nodes b. The Is uplink to another Branch Extender node question is asked only if this link has been defined as a limited resource and has also been defined as a Branch Extender uplink. Answer yes if the adjacent node is another Branch Extender. c.
APPN After the temporary list is built, it is always ordered so that configured next-hop CPs are first followed by CPs associated with similarly named known resources. Additional reordering may be performed. Once all the reordering is complete, the extended border node starts searching for the target resource one CP after another.
APPN Subnetwork visit count is the first of these, and describes the same concept as defined at the node level. When a port is first configured this parameter is initialized to the node setting. With this parameter you allow individual ports to deviate from the node level setting. Adjacent subnetwork affiliation is controlled by the other new extended border node prompt. This allows you to define whether or not the adjacent node is in the same network as the extended border node.
APPN memory, and APPN shared memory. See “APPN Node Tuning” on page 38 for a discussion of the APPN tuning parameters which control the amount of shared memory. Recall from the discussion under the set node prompt that configured routing lists are never modified by operational code. When the extended border node uses a given routing list it copies the next hop CP names into a temporary routing list.
APPN The class of service mapping table allows for the conversion of non-native COS names to native COS names and vice versa. Non-native networks using the same COS names as the extended border node’s native network need not have a COS mapping table defined. If only some of the non-native COS names differ from the native COS names, then only those that differ should be configured in a COS mapping table. A given COS mapping table may apply to a single or multiple non-native networks.
APPN COS name. Each COS mapping table may have one of these default COS mapping entries. You can never code a “*” as the native COS name. High-Performance Routing See Table 2 on page 25 for a list of ports that support HPR. See “Configuration Requirements for APPN” on page 26 for information about configuring the protocols that support APPN and HPR routing over direct DLCs on the router.
APPN APPN on the router uses a set of default TG characteristics for each port (or DLSw port). These defaults, defined by the default TG characteristics parameter apply to all the TGs for link stations defined on a port unless they are overridden for a particular link station by the modify TG characteristics parameter.
APPN are also three user-defined TG characteristics. You may define these user-defined TG characteristics in order to bias the route selection calculation in favor of certain paths. Note: For DLSw ports the TG characteristics that you define effect only the selection of routes between APPN nodes over these DLSw ports. These characteristics have no direct effect on any intermediate routing performed by DLSw on APPN’s behalf.
APPN v By manually setting the values of the maximum shared memory, percent of APPN shared memory to be used for buffers, and the maximum cached directory entries tuning parameters using the talk 6 option of the command line interface.
APPN v Module entry and exit traces specify component-level traces concerning the entry and exit of APPN modules. v General traces specify component-level traces concerning the APPN components. v Miscellaneous traces specify trace information about DLC transmissions and receptions.
APPN To enable collection implicitly, set create intermediate session records to yes. This setting will override the setting of collect intermediate session information. 2. Configuration changes to the APPN accounting parameters made using the talk 6 interface will not take effect until the router or the APPN function on the router is restarted. You can make changes interactively, however, by issuing SNMP set commands to modify the APPN MIB variables associated with the configuration parameters.
APPN 7. If the attempt to reach the primary DLUS is unsuccessful, attempt to reach the backup DLUS. Example: – Assume the following parameter values: - Delay before initiating retries = 120 sec – – – – - Perform short retries to restore disrupted pipe = yes - Short retry timer = 60 sec - Short retry count = 2 - Perform long retries to restore disrupted pipe = yes - Long retry timer = 300 sec Pipe activation fails. Wait 120 seconds (the value of Delay before initiating retries).
APPN – If this retry fails, wait 60 seconds (the value of Short retry timer). – Retry the primary DLUS. If this retry fails, retry the backup DLUS. This is attempt #1 of the Short retry count. – If this fails, wait 60 seconds (the value of Short retry timer). – Retry the primary DLUS, and then the backup DLUS. This is attempt #2 Short retry count. Short retry count is now exhausted. – If the retry still fails, wait 300 seconds (the value of Long retry timer). Then retry the primary DLUS.
APPN When configuring a DLSw port for APPN on the router, you assign the network node a unique MAC and SAP address pair that enables it to communicate with DLSw. The MAC address for the network node is locally administered and must not correspond to any physical MAC address in the DLSw network.
APPN Virtual Routing Node (VRN). This TG identifies the direct connection from the port to the connection network. The CP name of the VRN is the connection network name. Since the connectivity is represented by a TG from a given node to a VRN, normal topology and routing services (TRS) can be used by the network node server to calculate the direct path between any two nodes attached to the connection network.
APPN Figure 7. Single Connection Network using BAN with Multiple Frame Relay Ports Notes: 1. The same DLCI number must be specified on both ports. 2. The BDA address must be defined on the connection network definition. 3. The BNI addressees on both ports can be the same or different. 4. If the APPN node initiates the connection to the device, the APPN port that gets chosen for the connection is dependent upon which port responds first to the test frame. Example 3 Figure 8.

Chapter 3. Using AppleTalk Phase 2 This chapter describes the AppleTalk Phase 2 (AP2) configuration commands and includes the following sections: v “Basic Configuration Procedures” v “AppleTalk 2 Zone Filters” on page 214 v “Sample Configuration Procedures” on page 216 Basic Configuration Procedures This section outlines the initial steps required to get the AppleTalk Phase 2 protocol up and running.
Using AppleTalk Phase 2 designated as seed routers. Seed routers are configured with the network range and zone list while all other routers are given null values. Null values indicate that the router should query the network for values from the seed routers. For every network (segment) of your interconnected AppleTalk internet, at least one router interface must be configured as the seed router for that network. There are usually several seed routers on a network in case one of them fails.
Using AppleTalk Phase 2 The second identifier for the network is one or more ZoneNames. These ZoneName strings are not unique throughout the internet. The end station is uniquely identified by a combined object:type:ZoneName-string. A router first learns about a network when the new net range appears in the RTMP routing update from a neighboring router. The router then queries the neighbor for the ZoneNames of the new network.
Using AppleTalk Phase 2 Other Commands: You can use the AP2 CONFIG> list command to display all filter information for the interfaces. In addition, the list command accepts an interface# as an argument so that you can list information for only an interface. Sample Configuration Procedures This section covers the steps required to get AP2 up and running. For information on how to make further configuration changes, see “AppleTalk Phase 2 Configuration Commands” on page 221.
Using AppleTalk Phase 2 After you have specified the parameters, you can use the list command at the AP2 config> prompt to view your configuration. Setting Up Zone Filters Zone filtering lets you filter zones in each direction on each interface. To filter incoming packets, set up an input filter. To filter outgoing packets, set up an output filter. The interface will not readvertise filtered zone information in the direction that you define. Follow these steps to set up a zone filter: 1.
Using AppleTalk Phase 2 This excludes Manufacturing zone information from entering Router A, thereby filtering the zone from the rest of the internet. Example 2 The following example shows how to filter the Manufacturing zone from Network 11-15, but still allow the Manufacturing zone to be visible on Network 1-5. To do this, you would set up an output filter on Interface 3 of Router A to exclude Manufacturing zone information from being forwarded out of Interface 3.
Using AppleTalk Phase 2 Following are some examples that explain how to set up network filters in the internet, as shown in Figure 13.

Chapter 4. Configuring and Monitoring AppleTalk Phase 2 This chapter describes the AppleTalk Phase 2 (AP2) configuring and monitoring commands.
AppleTalk Phase 2 Configuration Commands (Talk 6) Add Use the add command to add the zone name to the interface zone list or to add the zone name to the interface zone list as the default for the interface or to add network and zone filters. Syntax: zone . . . add defaultzone . . . nfilter in . . . nfilter out . . . zfilter in . . . zfilter out . . . zone interface# zonename Adds the zone name to the interface zone list.
AppleTalk Phase 2 Configuration Commands (Talk 6) ap2config>add nfilter out Interface # [0]? 0 First Network range number (decimal) [0]? 11 Last Network range number (decimal) [0]? 20 zfilter in interface# zone name Adds a zone name filter to the input or output of the interface. Example: ap2config>add zfilter in Interface # [0]? 1 Zone name []? Marketing zfilter out interface# zone name Adds a zone name filter to the output of the interface.
AppleTalk Phase 2 Configuration Commands (Talk 6) Example: ap2config>delete nfilter in Interface # [0]? 1 Zone name []? Marketing zfilter out interface# zone name Deletes a zone name filter from the output of the interface. Example: delete zfilter out Interface # [0]? 1 Zone name []? Marketing interface Use this command to delete an interface. This is the only way to delete zone names that have non-printing characters.
AppleTalk Phase 2 Configuration Commands (Talk 6) Example: ap2config>disable nfilter in Interface # [0]? 2 nfilter out interface# Disables, but does not delete, the output network filters on this interface. Example: ap2config>disable nfilter out Interface # [0]? 2 zfilter in interface# Disables, but does not delete, the input zone filters on this interface.
AppleTalk Phase 2 Configuration Commands (Talk 6) ap2config>enable checksum interface interface# Enables the router to send AppleTalk Phase 2 packets over specific interfaces. Example: ap2config>enable interface 3 nfilter in exclusive or exclusive interface# Enables network input filters and controls how the filter is applied to the interface. Inclusive forwards matches.

AppleTalk Phase 2 Configuration Commands (Talk 6) node . . . cache-size value Cache-size corresponds to the total number of AppleTalk networks and nodes that can simultaneously communicate through this router using the fastpath feature. (Fastpath is a method of precalculating MAC headers to forward packets more quickly.) The default is 500, which allows up to 500 networks and nodes to simultaneously communicate through the router and still use fastpath.
AppleTalk Phase 2 Configuration Commands (Talk 6) ap2config>set node 2 2 Accessing the AppleTalk Phase 2 Monitoring Environment To access the AppleTalk Phase 2 monitoring environment, enter the following command at the + (GWCON) prompt: + protocol ap2 AP2> AppleTalk Phase 2 Monitoring Commands This section describes the AppleTalk Phase 2 monitoring commands which allow you to view the parameters and statistics of the interfaces and networks that transmit AppleTalk Phase 2 packets.
AppleTalk Phase 2 Monitoring Commands (Talk 5) Note: For many AppleTalk nodes, the network address (network number and node number) is dynamically assigned and might not be readily available. However, there are still a number of ways to use the atecho command effectively: 1. The AppleTalk address for router nodes is statically configured in many cases. Connectivity between router nodes is critical to overall network connectivity. 2.
AppleTalk Phase 2 Monitoring Commands (Talk 5) Next Hop The AppleTalk address of the next hop router used to forward a packet to the destination node, or Direct if the destination node is directly connected to the interface. Clear Counters The clear-counters command clears all cache usage counters and packet overflow counters. Syntax: clear-counters Counters Use the counters command to display the number of packet overflows on each network that sends and receives AppleTalk Phase 2 packets.
AppleTalk Phase 2 Monitoring Commands (Talk 5) Example: dump 0 View for interface 0 Dest net 214-214 153-153 152-152 Cost State 1 Good 0 Dir 0 Dir Next hop 152/152 Zone "eth-214" "eth153" "ser152" 3 entries Dest Net Specifies the destination network number, in decimal. Cost Specifies the number of router hops to this destination network. State Specifies the state of the entry in the routing table.
Chapter 5. Using VINES This chapter describes the commands to configure the Banyan VINES protocol and includes the following sections: v “VINES Overview” v “VINES Network Layer Protocols” on page 234 v “Basic Configuration Procedures” on page 239 v “Accessing the VINES Configuration Environment” on page 241 v “Running Banyan VINES on the Bridging Router” on page 239 v “VINES Configuration Commands” on page 241.
Using VINES router as a service network node for Vines. Banyan has assigned the range30800000 to 309FFFFF to IBM for use in its routers. This router uses the range 30900000 to 3097FFFF. Note: It is extremely important that no two routers be assigned the same network address. The network address for a Banyan service node is the 32-bit hexadecimal serial number of the service node. The subnetwork address for all service nodes is 1.
Using VINES v If the destination address does not equal the local VINES IP address or the broadcast address, VINES IP checks its routing tables for the next hop. If the hop count equals 0, VINES IP discards the packet. Otherwise, it decrements the hop count by one and forwards the packet to the next hop.
Using VINES Service nodes maintain two tables: a routing table and a neighbor table. Both of these tables have timers that age their contents to eliminate out-of-date entries. Routing updates for X.25 interfaces occur when there is a change in the routing database, for example, when a node goes up/down or the metric changes. Routing Table The routing table contains information about the service nodes. Figure 14 shows a sample routing table. Descriptions of the fields in this table follow the figure.
Using VINES Age (secs) The current age, in seconds, for the entry. If a router does not receive an update about a service node that is in the routing table at least every 360 seconds (6 minutes), the router removes the entry for that service node from the routing table. Neighbor Tables The neighbor table contains information about the neighbor service nodes and client nodes connected to the router. Figure 15 shows a sample neighbor table and descriptions of the fields in this table follow the figure.
Using VINES updates, spaced 90 seconds apart, are sent to the services nodes that sent the routing response packets. Once the X.25 interface receives routing response packets from all of the X.25 destination nodes, routing requests are no longer sent to those X.25 addresses. v RTP update packets. Packets sent by client nodes to the service nodes to notify the service nodes of their existence.
Using VINES Each client node maintains a timer that has a default setting of two seconds. The timer starts when a client node transmits a query request or assignment request packet. The client node stops and resets the timer when it receives a query response packet. When a timeout period exceeds two seconds, the client node initializes, broadcasts a query request packet, and resets the timer. Table 54 summarizes the states the service and client nodes enter during VINES ARP implementation. Table 54.
Using VINES To communicate across X.25 WANs, VINES servers directly connected to the WAN need these two options: Server-to-server WAN X.25 support on the server (hardware and software). Running Banyan VINES over WAN Links When you set up a PPP, Frame Relay, or X.25 link for use with VINES, you must set the HDLC speed of the link, even if you set the clocking to external. If you set the HDLC speed to zero, VINES assumes that the speed is 56 Kbps. Do not set the speed to a value that is faster than the line.
Chapter 6.
VINES Configuration Commands (Talk 6) handle user-configurable name that uniquely identifies each remote server. Example: add interface 0 4508907898 test Delete Deletes an X.25 address translation. Syntax: delete # interface ... Specifies the interface number. remote-X.25-addr Can include up to 15 digits. If the specified interface has not been configured using the VINES add interface command, the terminal displays the message That X.25 address has not been configured.
VINES Configuration Commands (Talk 6) vines checksumming interface# Enables checksumming on packets that the specified interface generates. Example: enable checksumming 0 interface interface# Enables the VINES protocol on the specified interface. Example: enable interface 1 vines Globally enables the VINES protocol. If you receive an error message after entering this command, contact your customer service representative. The VINES software may not be in your software load.
VINES Configuration Commands (Talk 6) VINES X.25 Configuration This information represents the following: Interface The interface that is configured for X.25. Remote X.25 Address The DTE address of the remote server. Remote Handle A user-configurable name that uniquely identifies the remote server. Set Use the set command to assign network addresses to routers in the VINES network and to specify the maximum number of client and service nodes. Syntax: client-node-neighbors ... set network-address ...
VINES Configuration Commands (Talk 6) number includes VINES servers and 2210s that are the first point-of-contact after crossing a WAN. The range is 1 to 65535, and the default is 50. Example: set service-node-neighbors 100 Accessing the VINES Monitoring Environment To access the VINES monitoring environment, * t 5 Then, enter the following command at the + prompt: + protocol vin VINES> VINES Monitoring Commands This section describes the VINES monitoring commands.
VINES Monitoring Commands (Talk 5) Net Unreachable The number of times the router received a packet destined for a node that was not found in the routing table. Hop Count Expired The number of times the router discarded a packet because its hop count expired. Routing Update from Orphan Client The number of times the router received an update packet from a client node whose service node does not exist.
VINES Monitoring Commands (Talk 5) seconds (6 minutes), the router removes the entry for that neighbor from the neighbor table and, if the neighbor is a service node, from the routing table. H/W Addr The node’s LAN address if the neighbor is connected to a LAN. If the frame relay protocol is running, the H/W Addr is the Data Link Connection Identifier (DLCI). For X.25 interfaces, the H/W Addr is the X.25 address of the neighbor. RIF Routing Information Field.
VINES Monitoring Commands (Talk 5) Age (secs) The current age, in seconds, for the entry. If a router does not receive a routing update about a service node that is in the routing table at least every 360 seconds (6 minutes), the router removes the entry for that service node from the routing table. Route Use the route command to view an entry from the routing table. Syntax: given address route given address The network address of the service node.
Chapter 7. Using DNA IV This chapter describes IBM’s implementation of Digital Network Architecture Phase IV (DNA IV) and includes the following sections: v “DNA IV Overview” v “IBM’s Implementation of DNA IV” on page 252 v “Configuring DNA IV” on page 261 v “DNA IV Configuration and Monitoring Commands” on page 265 DNA IV Overview DNA IV is a collection of software components that transfer information between networks connected by physical media.
Using DNA IV v DNA IV does not provide any Phase III compatibility features because it does not support the DDCMP data link protocols used by all Phase III nodes. v NCP (the router’s implementation of the DECnet Network Control Program) implements a subset of the original NCP commands and functions. DNA IV Terminology and Concepts This section contains a brief description of DNA IV terminology. Addressing Each node has a 16-bit node address, which is the same for all interfaces on that node.
Using DNA IV X.25 Data Link Addressing The router supports DECnet Phase IV over X.25 and can interoperate with routers running Digital’s implementation of DECnet Phase IV over X.25. You set up the local and the remote DTE address with the set/define circuit command when you set up a DECnet circuit. In the call-userdata parameter you specify the local DTE address in hexadecimal octets (characters). In the DTE-address parameter you specify the remote address in hexadecimal octets.
Using DNA IV Area Routers If the router is configured as an area router, it maintains a similar database for all of the areas up to the maximum area, and can exchange area routing information with other area routers. Areas are handled almost exactly the same as nodes, except messages give costs to areas, but not nodes. The areas concept results in two types of routing nodes: v A level 1 router only knows about one area, so it keeps track of nodes in its area. Also, it ignores adjacencies across areas.
Using DNA IV v Router NCP does not include the clear or purge commands, nor do the set commands have an all argument. The permanent database is always copied to the volatile database when the router starts, restarts, or boots. v A router NCP command can have only one argument. v NCP does not have the concept of lines. To see the data that a DECnet-VAX NCP show line command displays, use the GWCON interface and network commands.
Using DNA IV Access control prevents the forwarding of DNA IV (Long Format) data packets on the basis of source address, destination address, and interface. Access control does not affect routing packets, because they use a different packet format. This makes configuring access control safer, because you cannot break the routing protocol. To implement access control, addresses are masked and compared.
Using DNA IV nodes except node 1.9 because these two nodes share the same physical network. To configure the desired access control for this example, build an inclusive filter on interface Eth/0 of router 1.19 as shown in the bottom of Figure 16 1.2 1.4 1.20 1.22 1.23 Eth/0 1.19 PPP/0 1.13 1.9 Inclusive Filter Information Source Result Source Mask 1.2 1.4 0.0 Destination Result 63.1023 63.1023 0.0 1.13 1.13 1.9 Destination Mask 63.1023 63.1023 63.1023 Figure 16.
Using DNA IV Rest of Campus PPP/0 4.3 Eth/0 4.1 4.2 4.4 4.5 4.6 Exclusive Filter Information Source Result 0.0 Source Mask 0.0 Destination Result 4.4 Destination Mask 63.1023 Figure 17. Example of Exclusive Access Control Configure the desired access control for this example by building an exclusive filter on the PPP/0 interface of router 4.3 as shown in Figure 17. To configure the example given for router 4.
Using DNA IV Area routing filters allow you to configure a router to control the information about DECnet areas that are sent or accepted in level 2 routing messages. You may configure separate incoming and outgoing filters for each interface. Each filter specifies which areas routing information will be passed to or accepted from. When a network sends a level 2 routing update and there is a routing filter, the entry (RTGINFO) for any area not in the filter has the cost of 1023 and a hop count of 63.
Using DNA IV Area 22 Area 11 Area 7 Eth/1 13.1 Eth/0 13.2 13.3 13.4 13.5 Area 13 Figure 18. Example of Area Routing Filter for Security Blending DECnet Domains DECnet has a 16-bit node address space with a fixed hierarchy of 6 bits of area and 10 bits of node. By comparison, IP has a 32-bit node address space with a flexible multilevel hierarchy. Many established networks have now grown to the point where they use all 63 areas.
Using DNA IV Figure 19 on page 260 shows the areas that intersect are areas 1 and 2. The remainder of the areas can be duplicated between the two domains. In the example, there are two areas 3, 4, and 5, one in each domain. Note that it is never possible to allow direct connection between a node in area 3 in domain A and area 3 in domain B. The best that you can do is give the areas in the intersection the ability to talk to portions of each domain.
Using DNA IV done by configuring routers 1.18 and 2.21 to only accept routes to areas 3, 4, 6, and 8 from domain A. Routers 2.17 and 2.21 would only accept routes for areas 5 and 9 from domain B. Therefore, nodes in the intersection see a universe that contains areas 1 and 2 from the intersection, areas 3, 4, 6, and 8 from domain A, and areas 5 and 9 from domain B. To configure router 1.
Using DNA IV There is still no way that a node in domain A area 5 can communicate directly to a node in domain B area 5. For nodes in these two areas to communicate, you must do a series of application-level relays using the set host command. For example: v Run the set host command to remotely login from a node in the domain A area 5 to a node in domain A area 8. v Run the set host command to remotely login from a node in domain A area 8 to a node in area 1 or 2.

Using DNA IV Note: This example is for configuring a router to interoperate with other routers supporting the DEC-routing standard over X.25 networks. A router supporting the standard must be defined as type DEC-ROUTING-IV (level 1) or DEC-AREA (level 2). The default routing type is ROUTING-IV and AREA which allows interoperation with many existing IBM 2210 and other compatible routers.

DNA IV Configuration and Monitoring Commands 5. The zero command clears statistics saved in the volatile database, but does not clear the argument settings made with set or define commands. Define/Set This section explains both the define and the set commands. Use the define command to define access control lists and routing filters, and to define circuit, executor, and node parameters. Define is used to set SRAM (needs reboot). Syntax: circuit-specifier . . . define executor . . .
DNA IV Configuration and Monitoring Commands cost [range] Sets the cost to receive a packet on this circuit. This is used by the routing algorithm to determine the cost of a circuit in choosing routes (cost is not the same as an IP metric). Range: 1 to 25. Default: 4. The following values are suggested starting points: Circuit type Ethernet Token-Ring 4/16 Sync 56 Kb Sync T1 X.25 Cost 4 4 6 5 25 Example: define circuit tkr/0 cost 5 DTE Address Specifies the address of the remote DTE on the X.25 circuit.
DNA IV Configuration and Monitoring Commands The sum of maximum routers over all circuits should be less than the executor maximum broadcast routers argument, although this limit is not strongly enforced. recall timer Determines the delay in seconds between call attempts to establish an X.25 outgoing static circuit. For define, valid values are in the range 1 to 60 seconds. The default is 1 second. See also the argument maximum recalls. For set, valid values are in the range 0 to 65595 seconds.
DNA IV Configuration and Monitoring Commands verification Specifies whether the router compares a verification string on the router to verification data in an incoming initialization message. If they do not match, the X.25 circuit must be reinitialized. Specify enabled or disabled. executor argument Defines or sets arguments (that is, the executor) global to DNA in the permanent (define) or volatile (set) database.
DNA IV Configuration and Monitoring Commands maximum address number [range] (define only) Is the highest node address (within this area) for which routes will be kept by this router. The routing database will not include routes to nodes in this area with a higher node part of their address. Range: 1 to 1023. Default: 32. It should be higher than the highest node address in the router’s area. Setting it excessively large will affect the efficiency of the router, and will use excess memory.
DNA IV Configuration and Monitoring Commands This is used to detect packets which are in routing loops, which occur when routes decay. The maximum visits is 63. This is the default. This argument should be larger, by a factor of two, than both maximum hops and area maximum hops. state on Enables DNA.

DNA IV Configuration and Monitoring Commands area-specifier argument Examines the status of the volatile area routing database. This lets you find out what areas are reachable, and what the routes are to various areas. The options for the area-specifiers include the following: active areas Provides information on those areas which are currently reachable. all areas Provides information on all areas (up to the executor maximum area). area Provides information on the specified area.
DNA IV Configuration and Monitoring Commands next node Indicates the router that will be the next hop (intermediate destination) to the specified area. state Indicates that this will be reachable or unreachable. node-specifier argument Shows the status of the volatile node routing database; this includes information on the reachable nodes and the routes to them.

Chapter 9. Using OSI/DECnet V This chapter describes the router’s implementation of the International Standards Organization’s (ISO) Open Systems Interconnection (OSI) Connectionless Network Layer. DECnet Phase V supports OSI (hereafter called DECnet V/OSI) and users of DNA V networks can use this chapter for information about the ISO OSI protocols.
Using OSI/DECnet V Depending on the IS configuration, each IS can run three protocols: ES-IS, IS-IS, and Connectionless-Mode Network Protocol (CLNP). The ES-IS protocol enables the ESs and ISs attached to the same subnetwork to dynamically discover each other’s existence. An ES connected to the same subnetwork as an IS is adjacent to the IS. The IS-IS routing protocol enables the ISs to do the following: v Dynamically discover the existence and availability of adjacent ISs.
Using OSI/DECnet V The AFI specifies the type of IDI and the network addressing authority responsible for allocating the values of the IDI. The IDI specifies both the network addressing domain from which the values of the DSP are allocated and the network addressing authority responsible for allocating values of the DSP from that domain. DSP The network addressing authority identified by the IDI determines the DSP.
Using OSI/DECnet V GOSIP Version 2 NSAPs Government Open Systems Interconnection Profile (GOSIP) Version 2 provides for government use the NSAP addressing format illustrated in Figure 23. The authorities responsible for the address have clearly defined the fields and specified the addressing format under the DSP set by the National Institute of Standards and Technology (NIST).
Using OSI/DECnet V Table 59. IS-IS Multicast Addresses Destination Ethernet 802.3 Token-Ring 802.5 Address Description All ESs 09002B000004 C00000004000 For all end systems on the subnetwork. All ISs 09002B000005 C00000008000 For all intermediate systems on the subnetwork. All L2 ISs 0180C2000015 C00000008000 For all L2 intermediate systems on the subnetwork. All L1 ISs 0180C2000014 C00000008000 For all L1 intermediate systems on the subnetwork. OSI Routing OSI routes packets using the IS-IS protocol.
Using OSI/DECnet V IS-IS Domain An IS-IS domain is a set of rules, administered by the same authority, that all ESs and ISs must follow to ensure compatibility. There are two types of domains that require discussion, administrative domain and routing domain. Administrative Domain An administrative domain controls the organization of ISs into routing domains as well as the NSAP and subnetwork addresses that those routing domains use.
Using OSI/DECnet V Domain 1 L1 N1 N2 N4 N3 L1/L2 L2 L1 L1/L2 N3 N5 Area 1 Area 2 backbone Inter-Domain L1 N1 N2 N4 N3 L2 L1/L2 L1 L1/L2 N3 N5 Area 1 Area 2 backbone Domain 2 Figure 24. OSI Domain Synonymous Areas When an L1 IS services more than one area, these additional areas are called synonymous areas. A router can support any number of synonymous areas, as long as there is an overlap of at least one area address between adjacent routers.
Using OSI/DECnet V Synonymous Area N1 N2 L1 N1 N2 L1 L1 L1_A N3 Area 1 N3 Area 2 L2 L2 L1 N1 N1 N2 L1 L1 L1/L2 N3 N2 Area 3 N3 Synonymous Area Area 4 Figure 25. Synonymous Areas L1_A IS in area 2 must have area 1’s address added to its configuration and the L1 IS in area 1 must have area 2’s address added to its configuration. For areas 3 and 4 to be synonymous, each area’s address must be added to the others L1 IS.
Using OSI/DECnet V v v v v IS type (L1 only, or L1/L2) Priority LAN ID If applicable, the system ID of the L1 designated IS (pseudonode) Upon receiving this message, the adjacent L1 IS extracts the source ID of the sending IS. This IS then constructs its own IIH message and places its source ID into the source ID field. The sender’s source ID is placed into the IS neighbors field. Returning the sender’s ID verifies to the sender that the adjacent IS is aware that it exists (2-way adjacency).
Using OSI/DECnet V When more than one IS exists on a LAN, each IS compares the following to determine which IS will become the designated IS: v All ISs compare their priorities. The IS with the highest priority becomes the designated IS. v If the ISs have the same priority, they compare their source MAC addresses. The IS with the numerically highest MAC address becomes the designated IS for that LAN and is indicated through the LAN ID. Link State Databases Each L1 and L2 IS contains a link state database.
Using OSI/DECnet V v v v v v Source ID Set of area addresses that it services IS type (L2) System IDs and the cost of reaching IS adjacencies If applicable, the system ID of the pseudonode v Address prefixes for ISs located in an external domain L2 Link State Update (pseudonode) The L2 pseudonode LSU is multicast over the interface and propagated to all L2 ISs located outside the subnetwork.
Using OSI/DECnet V L2 Routing An L2 IS contains three routing tables: an L2 area-address routing table, an internal-metric reachable-address-prefix table (internal), and an external-metric reachable-address-prefix table (external). The following summarizes L2 routing: 1. An L2 IS receives a packet and compares the destination address in the header of the packet to the set of area addresses in the area address routing table. If a match exists, the packet is forwarded to the next hop backbone router.
Using OSI/DECnet V For example, a packet is destined to go from node A in domain 1 to node D in domain 2 ( Figure 26). Node A can choose two paths to send the packet, to node B and then on to D or to node C and then on to D. How nodes B and C advertise the cost of their routes to D determines how node A decides to route the packet, internally or externally. There are three possible options: v Nodes B and C advertise the cost of their routes to D as internal.
Using OSI/DECnet V 4700061234CCCC222222222222 The encoded address prefix is a result of the truncation of the NSAP 4700061234 The encoding rules are about all NSAP formats having a fixed length IDI and to any address prefix ending after the IDP. Encoding an AFI An address prefix based entirely on the AFI is encoded only on the 1 octet AFI field. For example, if an address prefix is needed for all X.121 format addresses (used on X.25 networks), you would use the X.121 AFI of 37.
Using OSI/DECnet V listing of the transmit password is not in the receive password database, the packet is dropped. There are three types of transmit and receive passwords: domain, area, and circuit. A domain password provides security for L2 routing information. An area password provides security for L1 routing information. A circuit password provides security for IS-IS hello messages.
Using OSI/DECnet V Routing Circuits Routing circuits are point-to-point connections between nodes that implement the ISO CLNS protocol. The router employs these types of routing circuits: v Static incoming circuits v Static outgoing circuits v Dynamically assigned circuits Static incoming and static outgoing circuits have only one SVC associated with them, and they carry both user data and non-user data (such as routing protocol messages).
Using OSI/DECnet V “initialization failure” may be generated on the static side due to non-response to its link initialization queries. The static SVC is then subsequently cleared. Templates A template is a collection of user configurable parameters for outgoing calls. It sets the parameters so that the circuit on the remote router accepts the incoming calls. The parameters defined in a template include the calling DTE address and the call/user data.
Using OSI/DECnet V consists of the router’s system ID and its area address. Use the list globals command to verify that the NET is configured correctly. Globally enabling OSI Enable the OSI software to run on the router using the enable OSI command. Use the list globals command to verify that the OSI protocol is enabled. Configuring OSI Over an Ethernet or a Token-Ring LAN To configure the OSI protocol to run over an Ethernet or over a Token-Ring LAN, set the subnet.
Using OSI/DECnet V Before beginning the steps below, use the appropriate preceding section to configure OSI over a LAN, X.25, or Frame Relay. 1. Enter the DN configuration process. Exit OSI config> and enter NCP>. Use the protocol DN command. 2. Define the global DNA address. Use the define executor address command to configure the DNA node and area number of the router. 3. Globally enable DNA. Use the define executor state command to enable the DNA protocol to run on the router. 4.

DECnet V/OSI Configuration Commands (Talk 6) area... filter... prefix-address receive-password routing-circuit... template... alias Adds an ASCII string that designates a particular area address or system ID. The ASCII string can be a-z, A-Z, 0-–9, a few other characters including the hyphen ( - ), comma ( , ), and underscore ( _ ). Do not use escape characters.
DECnet V/OSI Configuration Commands (Talk 6) The calling-DTE is the address of the calling router. The local router checks the DTE address of an incoming call against a prioritized list of filters for all circuits. A higher filter priority in the list means that a connection to that filter’s calling DTE address is made first. It is recommended that you assign a higher priority to filters for static circuits than for DA circuits. This can prevent an incoming static call from being assigned a DA circuit.

Chapter 11. Using NHRP This chapter describes how to use: v Next Hop Resolution Protocol (NHRP) as specified in Internet Draft Version 13, which has been submitted for RFC status. Next Hop Resolution Protocol (NHRP) Overview The Next Hop Resolution Protocol (NHRP) defines a method for a source station to determine the Non-Broadcast Multi-Access (NBMA) address of the “next hop” towards a destination.
Using NHRP includes the destination protocol address. The routers (that are also NHRP servers) along the routed path first check to see if the destination protocol address is an address that it can serve. If the router can satisfy the request, the router returns a Next Hop Resolution Reply with the NBMA address of the destination station. The originator can then establish a direct virtual circuit with the destination. If it cannot satisfy the request, the router forwards the request to the next-hop router.
Using NHRP information. So, for “one-hop” routing this operation happens once during transfer of a packet from its source to its destination. v The IBM implementation can operate in networks where some routers do not support NHRP. If the next-hop router is not capable of providing NHRP support, shortcut VCs can be established to the “last” server in the path. See “Disallowed Router-to-Router Shortcuts” on page 355 and “Exclude Lists” on page 354.
Using NHRP Figure 28. NHRP in a Classic IP Environment NHRP in a Classic IP Environment with non-NHRP Device This example shows how NHRP can be used between two 1577 devices. when one of them does not support NHRP. Here, Device2 provides the NHRP client with the ATM address of the non-NHRP device and the client can establish a shortcut for traffic to the non-NHRP host.
Using NHRP NHRP in a Pure LAN Emulation Environment In the LAN emulation case, routers use the IBM extensions to provide NBMA information for devices on their ELANs. When Device1 receives traffic from host A destined to host B, it originates a Next Hop Resolution Request and sends it on the routed path. Device2 replies to the request with NBMA information about host B, one of the stations that it serves because they are on the same ELAN.
Using NHRP This example also illustrates that the ELAN environment can be token-ring or Ethernet or any mixture of LAN types. Figure 31. NHRP in an ELAN Environment with LAN Switches NHRP in a Mixed Classical IP and ELAN Environment The NHRP function in the router can operate with both Classic IP and ELAN interfaces in the same network. In this example, the NHRP client supports the IBM extensions and can shortcut directly to the LEC destination for traffic in that direction. 350 MRS V3.
Using NHRP Figure 32. NHRP in a Mixed Classical IP and ELAN Environment NHRP to an Egress Router The source and/or destination stations of protocol traffic do not have to belong to subnets served by NHRP participants. They may access the ATM network via routers that communicate with the NHRP devices. In this case, the 2210 provides shortcuts through the ATM network to eliminate as many hops as possible. Figure 33. NHRP to an Egress Router Chapter 11.
Using NHRP NHRP Implementation NHRP interacts with the router function in the router. When the router function in the router is forwarding packets along the routed path and NHRP successfully obtains a shortcut VC, NHRP will update the router function to send the packet directly over the shortcut VC. NHRP updates the routing function’s forwarding table after the VC is up. This allows the switch from routed path to the shortcut path to occur without any packet loss.
Using NHRP By default, the LSI will use the MAC address burned into the associated ATM adapter as the source MAC address of frames transmitted over the LANE shortcut VCCs. It is possible, though unlikely, that this could confuse some end-station protocol stack implementations, since the MAC address will not match that of the router that the end-station uses as a gateway to transmit packets to the associated IP address.
Using NHRP NHRP Auto-Configuration NHRP is enabled by default if IP is present in the box. It can be disabled by entering the disable NHRP command from the NHRP config> prompt. See “Accessing the NHRP Configuration Process” on page 359 for additional information. When using an existing configuration file, NHRP is enabled by default if it was not previously configured. The configuration file will be automatically updated at runtime to create NHRP shortcut interfaces.
Using NHRP Extensions The NHRP protocol includes Extensions. Extensions are appended to NHRP packets. Extensions are used to request additional functions from the NHRP participants. The use of the extensions parameter lets you determine if the router sends certain extensions: v path information extensions v IBM vendor-private extensions Path Information Extensions: Three extensions are defined in NHRP to provide path information.
Using NHRP To illustrate how to specify disallowed R2R shortcuts using protocol addresses and masks, consider the following network diagram: 1.1.1.4 ATM nhs 1.1.1.5 1.1.1 9.9.9.5 Router1 9.9.9.3 9.9.9 Router2 Other IP subnets host1 9.9.9.1 host2 9.9.9.2 Figure 34. Using Disallowed Router-to-Router Shortcuts Example 1: An entry with address=9.9.9.1 mask=255.255.255.255 would cause the NHS to send a NAK to the sender of a Next Hop Resolution Request with destination protocol address 9.9.9.
Using NHRP Selecting the destination only option causes the router to deny shortcut requests from any NHRP client if any IP packets are being filtered to the destination address. If NHRP clients should not be trusted, destination only should be selected. destination only might be the best option when NHRP clients are non-routers with multiple IP addresses or non-router clients that transmit packet that originate from other sources.
Using NHRP address, the selector, are assigned dynamically after the router is activated (and may change if the configuration of the router changes), unless you have configured a specific selector. You can specify the ATM address, including selector, by entering prot arp at the talk 6 Config> prompt, followed by add atm, giving the desired IP address and then specifying a selector. This is the same procedure used to define an ATMARP client.
Chapter 12. Configuring and Monitoring NHRP This chapter describes how to configure and monitor the Next Hop Resolution Protocol (NHRP). For a description of this protocol, refer to “Next Hop Resolution Protocol (NHRP) Overview” on page 345.

Specify a protocol address which must be excluded from the NHRP network.
NHRP Advanced Configuration Commands (Talk 6) exclude list Deletes an exclude list entry. This option deletes an exclude list entry and prompts you to delete the entry from the disallowed router-to-router shortcuts. See “NHRP Access Controls” on page 357 for more information. You must specify an index which must be deleted. Use the list exclude command to determine the right index. Example: del exc Enter index of access control to be deleted [1]? # Address Mask 1 6.6.6.6 255.255.255.

Using this option essentially disables the client function in the router.
NHRP Advanced Configuration Commands (Talk 6) to the next hop along the routed path.) Once the traffic rate exceeds the threshold, the router tries to establish a shortcut. If it can successfully create a shortcut path, the path is used even if the traffic drops below the threshold. The path continues to be used until the traffic stops for a period of time. This is done to avoid going back and forth from the routed path to the shortcut path if traffic is sporadic. Valid values: Minimum 1 packet/second.

Chapter 13. Using IP Version 6 (IPv6) This chapter describes how to use IPv6. IPv6 Overview IP Version 6 (IPv6) is a new version of the Internet Protocol. It is designed as a successor to IP Version 4 (IPv4). The following list identifies some of the advantages provided by IPv6: v Large address space IPv6 uses a 128-bit address. v Routing Using the large address size, IPv6 provides an hierarchical address scheme which allows you to create a flexible routing hierarchy.
Using IPv6 Broadcast addressing has been replaced by multicast addressing in IPv6. IPv6 Address Format The IPv6 address is composed of 128 bits. These bits are written as eight 16-bit integers separated by colons. Example: ABCD:1234:0000:1234:5555:FFEE:7777:0123 You can use the following simplifying rules: v Skip leading zeroes. Example: ABCD:1234:0:1234:0:FFEE:7777:123 v Inside an address, a set of consecutive, null 16-bit numbers can be replaced by two colons.
Using IPv6 IPv6 Minimum MTU The minimum MTU for IPv6 is 1280 bytes. You cannot enable IPv6 on an interface with an MTU less than 1280 bytes. IPv6 Mandatory Path MTU Discovery Path MTU Discovery is a protocol that allows a host to determine the maximum size packet that will successfully traverse a path to a destination without fragmentation. As packets are generated and sent from the host, the MTU of the particular output interface that the packet will be transmitted to is available.
Using IPv6 4. Use the set acc on command at the IPv6 Config> prompt to enable access control. IPv6 Neighbor Discovery Protocol (NDP) IPv6 uses NDP to perform autoconfiguration. NDP allows IPv6 nodes on the same link to discover each other’s presence, to determine each other’s link-layer addresses, to find routers, and to maintain reachability information about the paths to active neighbors.
Using IPv6 Redirect If the source address of the packet and the next hop are on the same network, a router may send a redirect message informing the sender that the next hop is a neighbor. Use the p ndp command at the Config> prompt to configure NDP parameters. IPv6 over IPv4 Tunneling IPv6 over IPv4 tunneling allows you to migrate from IPv4 networks to IPv6 networks without the need to simultaneously upgrade all equipment to IPv6 support.
Using IPv6 the reverse path forwarding calculation on a received multicast datagram. Reverse path forwarding (rpf) is used to validate whether the received multicast datagram arrived on an interface that would be valid for forwarding to the source address contained in the multicast datagram.

Appendix B. Packet Sizes This appendix discusses the sizes of packets for the various networks and protocols supported. Included are the following sections: v General Issues v Network-Specific Size Limits v Protocol-Specific Size Limits v Changing Maximum Packet Sizes General Issues For the purposes of this discussion, the packets that the routers handle consist of user data and header information. The amount of user data within a packet is limited by the amount of header information on the packet.
Packet Sizes Note: You can change the maximum packet size for interfaces other than Ethernet. Use the network command from the Config> prompt to access the interface’s configuration commands. The maximum packet size is the maximum amount of data the protocol forwarder can pass to the device. Note: These numbers correspond to the MTUs in 4.2 BSD UNIX. For an IP packet, this includes the IP header, the UDP or TCP header, and all data.

In Open Systems Interconnection (OSI) architecture, the layer that is responsible for routing, switching, and link-layer access across the OSI environment. network management. The process of planning, organizing, and controlling a communication-oriented data processing or information system. network management station.
packet loss ratio. The probability that a packet will not reach its destination or not reach it within a specified time. terminal equipment (DTE). Call-establishment protocols are not required. Contrast with switched virtual circuit (SVC). packet mode operation. Synonym for packet switching. physical circuit. A circuit established without multiplexing. See also data circuit. Contrast with virtual circuit. packet switching.
private branch exchange (PBX). A private telephone exchange for transmission of calls to and from the public telephone network. problem determination. The process of determining the source of a problem; for example, a program component, machine failure, telecommunication facilities, user or contractor-installed programs or equipment, environmental failure such as a power loss, or user error. program temporary fix (PTF).
rlogin (remote login). A service, offered by Berkeley UNIX-based systems, that allows authorized users of one machine to connect to other UNIX systems across an internet and interact as if their terminals were connected directly. The rlogin software passes information about the user’s environment (for example, terminal type) to the remote machine. RNR packet.
segment. (1) A section of cable between components or devices. A segment may consist of a single patch cable, several patch cables that are connected, or a combination of building cable and patch cables that are connected. (2) In Internet communications, the unit of transfer between TCP functions in different machines. Each segment contains control and data fields; the current byte-stream position and actual data bytes are identified along with a checksum to validate received data. segmenting.
focal point. An APPN end node can be a SOC node if it supports the function to exchange management services capabilities. split horizon. A technique for minimizing the time to achieve network convergence. A router records the interface over which it received a particular route and does not propagate its information about the route back over the same interface. spoofing.
problem determination requests, and providing directory services and other session services for users of the network. Multiple SSCPs, cooperating as peers with one another, can divide the network into domains of control, with each SSCP having a hierarchical control relationship to the physical units and logical units within its own domain. Systems Network Architecture (SNA).
Transmission Control Protocol/Internet Protocol (TCP/IP). A set of communications protocols that support peer-to-peer connectivity functions for both local and wide area networks. transmission group (TG). (1) A connection between adjacent nodes that is identified by a transmission group number. (2) In a subarea network, a single link or a group of links between adjacent nodes.
VIrtual NEtworking System (VINES). The network operating system and network software from Banyan Systems, Inc. In a VINES network, virtual linking allows all devices and services to appear to be directly connected to each other, when they may actually be thousands of miles apart. See also StreetTalk. virtual route (VR).
