Enable RIP
This example shows the minimum configuration required to enable RIP on an interface. R1 and R2 are two routers connecting to network 10.10.11.0/24. R1 and R2 are also connected to networks 10.10.10.0/24 and 10.10.12.0/24, respectively. To enable RIP, first define the RIP routing process, then associate a network with the routing process.
Topology
Figure 2-3: Enable RIP Topology
R1
#configure terminal | Enter configure mode. |
|---|---|
(config)#router rip | Define a RIP routing process, and enter Router mode. |
(config-router)#network 10.10.10.0/24 (config-router)#network 10.10.11.0/24 | Associate networks with the RIP process. |
(config-router)#exit | Exit router mode and return to configure mode. |
(config)#commit | Commit the candidate configuration to the running configuration |
R2
#configure terminal | Enter configure mode. |
|---|---|
(config)#router rip | Define a RIP routing process, and enter Router mode. |
(config-router)#network 10.10.11.0/24 (config-router)#network 10.10.12.0/24 | Associate networks with the RIP process. |
(config-router)#exit | Exit router mode and return to configure mode. |
(config)#commit | Commit the candidate configuration to the running configuration |
