Configuration Example

An example of configuring RIPv2 is shown in Fig. 5-2. Host A and Host B should be able to communicate with each other with an RIP route. Host A and Host B should be able to communicate with the gateway (e.g., access Internet) with RIP.

Configuring Switch A

For Switch A, configure 2 VLAN interfaces for networks 10.10.1.1/24 and 10.10.3.1/24. Then, configure an RIP interface in network 10.10.3.1/24. Switch A should accept the default route, which is advertised by Switch C.

Configuring Switch B

Configure 2 VLAN interfaces for networks 10.10.1.1/24 and 10.10.3.1/24. Then, configure an RIP interface in network 10.10.3.1/24. Switch B should accept the default route, which is advertised by Switch C.

Configuring Switch C

Configure 3 VLAN interfaces for networks 10.10.3.2/24, 10.10.4.2/24, and 10.10.5.2/24. Then, configure a default route and 2 RIP interfaces.

Verifying the RIP Configuration

Verify the RIP configuration of the switches as shown below. (In the following example, the RIP peer and the RIP route table in Switch A is verified.)

admin@XorPlus# run show rip peer
