RIP
Use this menu to enable RIP on the LAN interface.
Proxy ARP
This feature allows the network portion of a group of addresses to be shared among several physical
network segments. The ARP protocol provides a way for devices to create a mapping between physical
addresses and logical IP addresses. Proxy ARP makes use of this mapping feature by instructing a
router to answer ARP requests as a "proxy" for the IP addresses behind one of its ports. The device
which sent the ARP request will then correctly assume that it can reach the requested IP address by
sending packets to the physical address that was returned. This technique effectively hides the fact that
a network has been (further) subnetted. If this option is set to
YES, when an ARP request is received on
the Ethernet port the address is looked up in the IP routing table. If the forwarding port is not on the
Ethernet port and the route is not the default route, the Total Access 600 will answer the request with its
own hardware address.
MAC Address
This is a read-only MAC address programmed at ADTRAN.
MODE
Enables or disables RIP.
PROTOCOL
Specifies the RIP protocol. Choices are V1
(def) (which is RIP version 1) or
V2 (RIP
version 2).
METHOD
Specifies the way the RIP protocol sends
out its advertisements. Choices are given
below.
NONE
All routes in the router table are advertised
with no modification of the metrics.
SPLIT HORIZON
Only routes not learned from this circuit are
advertised.
POISON REVERSE (def)
All routes are advertised, but the routes
learned from this port are “poisoned” with an
infinite metric.
DIRECTION
Allows the direction at which RIP
advertisements are sent and listened to be
specified.
TX AND RX (def)
RIP advertisements are periodically
transmitted and are listened to on this port.
TX ONLY
RIP advertisements are periodically
transmitted but are not listened to on this
port.
RX ONLY
RIP advertisements are not transmitted on
this port, but are listened.
V2 SECRET
Enter the secret used by RIP version 2 here.
