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
< (6 , 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.
M ODE Enables or disables RIP.
P ROTOCOL Specifies the RIP protocol. Choices are V1 (def)
(which is RIP version 1) or V2 (RIP version 2).
M ETHOD Specifies the way the RIP protocol sends out its
advertisements. Choices are given below.
N ONE All routes in the router table are advertised
with no modification of the metrics.
S PLIT H ORIZON Only routes not learned from this circuit are
advertised.
P OISON R EVERSE GHI All routes are advertised, but the routes
learned from this port are “poisoned” with an
infinite metric.
D IRECTION Allows the direction at which RIP advertise-
ments are sent and listened to be specified.
TX AND RX GHI RIP advertisements are periodically
transmitted and are listened to on this port.
TX O NLY RIP advertisements are periodically
transmitted but are not listened to on this
port.
RX O NLY RIP advertisements are not transmitted on
this port, but are listened.
V2 S ECRET Enter the secret used by RIP version 2 here.
