Introducing HP-UX Mobile IPv6 1 Introducing HP-UX Mobile IPv6 This chapter introduces and describes HP-UX Mobile IPv6 functionality and operation.
Introducing HP-UX Mobile IPv6 Overview Overview The HP-UX Mobile IPv6 product delivers mobility support for HP-UX IPv6 by providing Home Agent and Correspondent Node functionality for HP-UX 11i version 1 and 2 servers. HP-UX Mobile IPv6 is based on the following IETF standards, which can be found at http://www.ietf.
Introducing HP-UX Mobile IPv6 Overview Comparison of Mobile IPv4–Mobile IPv6 The following information might be helpful if you are migrating from Mobile IPv4 to Mobile IPv6, or if you understand Mobile IPv4 and want to preview Mobile IPv6 by comparing the two distinct technologies. The following is a list of the major differences between Mobile IPv4 and Mobile IPv6 concepts; refer to IETF documentation for complete information.
Introducing HP-UX Mobile IPv6 Mobile IPv6 Architecture Mobile IPv6 Architecture IPv6 addresses are topologically correct, therefore nodes attached to the same physical network or LAN segment must have the same IPv6 network address prefix. Mobile IPv6 provides transparent routing of IP data-packets to a mobile IP device or node, such as a portable computer, regardless of the mobile node’s point of attachment to the network.
Introducing HP-UX Mobile IPv6 Mobile IPv6 Architecture Home Agents and Basic Operation In Mobile IPv6 basic operation, a Correspondent Node sends data-packets to the Mobile Node using the Mobile Node’s home address. A Home Agent (HA), a node or router on the Mobile Node’s home network, intercepts these data-packets and tunnels them to the Mobile Node’s current Care-of Address, as show in Figure 1-1, Correspondent Node to Mobile Node in Basic Operation.
Introducing HP-UX Mobile IPv6 Mobile IPv6 Architecture Route Optimization In addition to basic operation, Mobile IPv6 can operate using Route Optimization. Route Optimization improves data transmission rates between the Correspondent Node and Mobile Node. With Route Optimization, the Mobile Node and Correspondent Node communicate directly with each other and bypass the Home Agent. Route Optimization is especially beneficial when the Mobile Node and Correspondent Node are in the same network.
Introducing HP-UX Mobile IPv6 Establishing Basic Operation Establishing Basic Operation In most cases, the Mobile Node and Correspondent Node communicate using Route Optimization. Mobile IPv6 basic operation is used in initial communication, when the Correspondent Node does not have information about the Mobile Node’s Care-of Address, and in cases where the Correspondent Node does not support Mobile IPv6 Route Optimization.

Introducing HP-UX Mobile IPv6 Establishing Basic Operation Mobile Node Acquires Care-of Address When the Mobile Node attaches to a new foreign network, it gets a new Care-of Address using a stateless (IPv6 stateless autoconfiguration) or stateful (such as DHCPv6) method. The Care-of Address has the network prefix of the foreign network. Mobile Node Sends Binding Update to Home Agent After the Mobile Node determines its Care-of Address, it sends a Binding Update message to its Home Agent.
Introducing HP-UX Mobile IPv6 Establishing Basic Operation Basic Operation Data Paths Mobile Node to Correspondent Node Data Path in Basic Operation In basic operation mode, the Mobile Node sends data-packets to the Correspondent Node through its Home Agent using the following procedure, and as shown in Figure 1-6, Data Path: Mobile Node to Correspondent Node in Basic Operation: 1.
Introducing HP-UX Mobile IPv6 Establishing Basic Operation Correspondent Node to Mobile Node Data Path in Basic Operation In basic mode, the Correspondent Node sends data-packets back to the Mobile Node through the Mobile Node’s home address using the following procedure, and as shown in Figure 1-7, Data Path: Correspondent Node to Mobile Node in Basic Operation: 1. The Correspondent Node addresses the data-packet to the Mobile Node’s home address. 2.
Introducing HP-UX Mobile IPv6 Establishing Route Optimization Establishing Route Optimization Route Optimization improves data transmission rates between the Correspondent Node and Mobile Node. Without Route Optimization, data-packets from the Correspondent Node to the Mobile Node are sent to the Home Agent (and through the Mobile Node’s home network). With Route Optimization, the Correspondent Node sends data-packets directly to the Mobile Node’s Care-of Address.

Introducing HP-UX Mobile IPv6 Establishing Route Optimization Mobile Node Sends Care-of Test Init and Home Test Init Messages The Care-of Test Init message is addressed directly to the Correspondent Node. The Home Test Init message is routed through the Home Agent. These messages are routed over different network segments in most topologies. Correspondent Node Sends Care-of Test and Home Test Messages The Correspondent Node sends Care-of Test and Home Test messages back to the Mobile Node.
Introducing HP-UX Mobile IPv6 Establishing Route Optimization Route Optimization Data Paths Mobile Node to Correspondent Node Data Path in Route Optimization In route optimization mode, the Mobile Node sends data-packets directly to the Correspondent Node. The Mobile Node uses its Care-of Address as the source IP address and puts its home address in a special IPv6 header option for Mobile IPv6—the Home Address destination option.
Introducing HP-UX Mobile IPv6 Establishing Route Optimization Correspondent Node to Mobile Node Data Path in Route Optimization In route optimization mode, the Correspondent Node sends data-packets directly to the Mobile Node. The Correspondent Node uses the Mobile Node’s Care-of Address as the destination IP address and puts the Mobile Node’s home address in a special IPv6 routing header for Mobile IPv6, a Type 2 routing header.
Introducing HP-UX Mobile IPv6 Returning Home and Deregistering Returning Home and Deregistering When a Mobile Node moves back to its home network, it determines whether it is attached to its home network based on the network prefix information it receives in the Router Advertisements sent by Home Agents on the home link. The Mobile Node deregisters by sending a special Binding Update to its Home Agent to tell the Home Agent it is now attached to the home network.
Introducing HP-UX Mobile IPv6 Dynamic Home Agent Address Discovery Dynamic Home Agent Address Discovery When attached to a Foreign Network, a Mobile Node might not know the address of its Home Agent. For example, a router operating as the Mobile Node's Home Agent might get reconfigured or replaced by a different node serving as a Home Agent on the home network.
Introducing HP-UX Mobile IPv6 Prefix Discovery Prefix Discovery Prefix Discovery allows a Mobile Node to get network prefix information about its Home Network and to configure its Home Address if needed. The Home Agent monitors prefix information from Router Advertisement messages on the Home Network. The Mobile Node can request prefix information by sending a Mobile Prefix Solicitation message to the Home Agent.

Configuring HP-UX Mobile IPv6 Configuring Mobile IPv6 Correspondent Nodes Configuring Mobile IPv6 Correspondent Nodes Use the following steps to configure Mobile IPv6 Correspondent Nodes after installing HP-UX Mobile IPv6 on a system: Step 1. Use the mip6config tool to configure the parameters in the mip6mod configuration file. Refer to Chapter 4, “Creating Mobile IPv6 Kernel Module Configuration Files with the mip6config Tool,” on page 45, for more information. Step 2.
Configuring HP-UX Mobile IPv6 Configuring Mobile IPv6 Home Agents Configuring Mobile IPv6 Home Agents At least one router node on the Mobile Node’s home link must be a Home Agent to allow a Mobile Node to remain reachable while away from it is away the home link. As described in “The Router Advertisement Daemon: rtradvd” on page 38,, the rtradvd determines if a system is Home Agent—not mip6mod. The rtradvd and mip6mod must be running on Home Agents.
Configuring HP-UX Mobile IPv6 Configuring Mobile IPv6 Home Agents Configuring Dynamic Home Agent Address Discovery As described in configure in “Dynamic Home Agent Address Discovery” on page 18, a Mobile Node only needs a home network prefix configured and it can dynamically find the address of a Home Agent on its home network when it needs to register its Care-of Address. To enable Dynamic Home Agent Address Discovery, you must configure a Mobile IPv6 anycast address on the Home Agent loop-back interface.
