Troubleshooting RIP

RIP
RIP is a broadcast protocol so it can only exchange routing information with
non-broadcasting networks in unicast mode. This example shows how to
configure RIP message unicasting.
Router A connects Router B and Router C with serial lines in non-broadcasting
networks. Router A (192.1.1.2) only wants to send the routing updating
information to the adjacent Router B (192.1.1.2) without sending the information
to Router C.

To configure RIP unicast:
1 Configure RIP on Router A:
[RouterA] rip
[RouterA-rip] network 192.1.1.0
2 Configure Router A's unicast peer to be Router B.
[RouterA-rip] peer 192.1.1.2
3 Configure serial interface Serial 0
[RouterA-rip] interface serial 0
[RouterA-Serial0] ip address 192.1.1.1 255.255.255.0
No updating messages can be received when the physical connection works well.
This may have the following cause:
RIP is not running on the corresponding interface (maybe the
command has been executed), or this interface is not included with the
command. Multicasting has been configured on the opposite router
network
(perhaps
rip version 2 multicast
