本文演示了如何在两台路由器R1和R2之间配置RIP版本2路由协议，实现不同子网间的通信。重点介绍了配置步骤、路由表显示结果及验证过程。

CCNA--LAB-2 ：配置 RIP 路由协议 <?xml:namespace prefix = v ns = "urn:schemas-microsoft-com:vml" /><?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

拓扑如上：

R1 ：

Router>en
Router#conf t
Router(config)#hostname R1
R1(config)#int
R1(config)#interface f0/0
R1(config-if)#ip address 192.168.1.254 255.255.255.0
R1(config-if)#no sh
R1(config-if)#int f0/1
R1(config-if)#ip add
R1(config-if)#ip address <?xml:namespace prefix = st1 ns = "urn:schemas-microsoft-com:office:smarttags" />12.1.1.1 255.255.255.0
R1(config-if)#no sh
R1(config-if)#exit
R1(config)#router rip    -- 进入并启用 RIP 配置模式
R1(config-router)#version 2    -- 指定版本 2
R1(config-router)#no auto-summary    -- 不要自动汇总
R1(config-router)#network 12.1.1.0    -- 宣告直连的网段
R1(config-router)#network 192.168.1.0   -- 宣告直连的网段
R1(config-router)#end

查看路由表：
R1#show ip route
Codes: C - connected, S - static, I - IGRP, 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, E - EGP
       i - IS-IS, 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 route

Gateway of last resort is not set

     12.0.0.0/24 is subnetted, 1 subnets
C       12.1.1.0 is directly connected, FastEthernet0/1
C    192.168.1.0/24 is directly connected, FastEthernet0/0
R     192.168.2.0/24 [120/1] via 12.1.1.2, 00:00:04, FastEthernet0/1

R 是通过 RIP 路由学习到 192.168.2.0/24 网段

R2 ：

Router(config)#hostname R2
R2(config)#interface f0/1
R2(config-if)#ip address 12.1.1.2 255.255.255.0
R2(config-if)#no sh
R2(config)#interface f0/0
R2(config-if)#ip address 192.168.2.254 255.255.255.0
R2(config-if)#no sh
R2(config-if)#exit
R2(config)#router rip
R2(config-router)#version 2
R2(config-router)#no auto-summary
R2(config-router)#network 192.168.2.0
R2(config-router)#network 12.1.1.0
R2(config-router)#end

R2#show ip route
Codes: C - connected, S - static, I - IGRP, 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, E - EGP
       i - IS-IS, 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 route

Gateway of last resort is not set

     12.0.0.0/24 is subnetted, 1 subnets
C       12.1.1.0 is directly connected, FastEthernet0/1
R    192.168.1.0/24 [120/1] via 12.1.1.1, 00:00:20, FastEthernet0/1
C    192.168.2.0/24 is directly connected, FastEthernet0/0

验证在 PC0 上拼 PC1 ：
