IP Map/Link IP Address
Write security: 3, Read security: 5
The virtual circuit may require an IP address to be specified at this
DLCI, or numbered, interface. This address is used by the Router
Option Module to respond to Inverse ARP requests. If this IP ad-
dress is left as 0.0.0.0, the link is treated as unnumbered and the
Router Option Module responds to the Inverse ARP with its Ether-
net IP address.
IP Map/RIP Protocol
Write security: 3, Read security: 5
The RIP protocol can be specified per DLCI. The selections are:
Off (meaning no RIP packets are listened to or sent)
V1 (def) (which is RIP version 1)
V2 (which is RIP version 2)
IP Map/RIP Method
Write security: 3, Read security: 5
The method of which the RIP protocol is used is specified here:

tised out this virtual circuit with no modi-
fication of the metrics.

lar virtual circuit are advertised.
