and the Express 4100/4110 responds to the Inverse ARP with its
Ethernet IP address.
IP Map/RIP Protocol
Write security: 3, Read security: 5
The RIP protocol can be specified per DLCI. The possible selections
are Off (meaning no RIP packets are listened to or sent), V1 (def)
(which is RIP version 1) or V2 (which is RIP version 2).

Split Horizon (def) Only routes not learned from this particu-
lar virtual circuit are advertised.
Poison Reverse All routes are advertised, but the routes
learned from this port are “poisoned” with
an infinite metric.
Tx and Rx (def) RIP advertisements are periodically trans-
mitted and are listened to on this virtual
circuit.
Tx Only RIP advertisements are periodically trans-
mitted but are not listened to on this vir-
