422CHAPTER 28: CONFIGURING RIP

RIP - Unicast	RIP is a broadcast protocol so it can only exchange routing information with
Configuration	non-broadcasting networks in unicast mode. This example shows how to
Example	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.
	Figure 145 Networking diagram of configuring the RIP unicast
	Router A	s0 192.1.1.1
		RouterA unicasts the

		information to RouterB
		s0 192.1.1.2
	Router C	Router B

To configure RIP unicast:

1Configure RIP on Router A:

[RouterA] rip

[RouterA-rip]network 192.1.1.0

2Configure Router A's unicast peer to be Router B.

[RouterA-rip] peer 192.1.1.2

3Configure serial interface Serial 0

[RouterA-rip]interface serial 0

[RouterA-Serial0]ip address 192.1.1.1 255.255.255.0

Troubleshooting RIP 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 undo rip work command has been executed), or this interface is not included with the network command. Multicasting has been configured on the opposite router (perhaps rip version 2 multicast command has been executed), but not configured on the local router.
