Command
Router Rip
Use
The router rip command is necessary to enable RIP. RIP must be enabled before carrying out any of the RIP commands.
Syntax
R1(config)#router rip
Example
The following example demonstrates the router rip command. First, the show ip route command is issued to help determine the network layout.
R1#sh ip route Codes: C – connected, S – static, R – RIP, M – mobile, B – BGP D – EIGRP, EX – EIGRP external, O – OSPF, IA – OSPF inter area N1 – OSPF NSSA external type 1, N2 – OSPF NSSA external type 2 E1 – OSPF external type 1, E2 – OSPF external type 2 i – IS-IS, su – IS-IS summary, L1 – IS-IS level-1, L2 – IS-IS level-2 ia – IS-IS inter area, * – candidate default, U – per-user static route o – ODR, P – periodic downloaded static routeGateway of last resort is not set 1.0.0.0/32 is subnetted, 1 subnets C 1.1.1.1 is directly connected, Loopback0 10.0.0.0/24 is subnetted, 2 subnets C 10.1.1.0 is directly connected, FastEthernet0/0 R1#
Next, router rip is configured on R1.
R1(config)#router rip R1(config-router)#version 2 R1(config-router)#no auto R1(config-router)#network 10.1.1.0 R1(config-router)#exit R1(config)#exit R1#
After that, it is configued on R2.
R2(config)#router rip R1(config-router)#version 2 R1(config-router)#no auto R2(config-router)#network 10.1.1.0 R2(config-router)#exit R2(config)#exit R2#
Now, if we type show ip route we see that RIP is enabled and sending routes
R1#sh ip route Codes: C – connected, S – static, R – RIP, M – mobile, B – BGP D – EIGRP, EX – EIGRP external, O – OSPF, IA – OSPF inter area N1 – OSPF NSSA external type 1, N2 – OSPF NSSA external type 2 E1 – OSPF external type 1, E2 – OSPF external type 2 i – IS-IS, su – IS-IS summary, L1 – IS-IS level-1, L2 – IS-IS level-2 ia – IS-IS inter area, * – candidate default, U – per-user static route o – ODR, P – periodic downloaded static routeGateway of last resort is not set 1.0.0.0/32 is subnetted, 1 subnets C 1.1.1.1 is directly connected, Loopback0 10.0.0.0/24 is subnetted, 2 subnets R 10.2.2.0 [120/1] via 10.1.1.2, 00:00:06, FastEthernet0/0 C 10.1.1.0 is directly connected, FastEthernet0/0 R1#
