一、拓扑图如下：
二、RIP协议配置：
[R1]rip [R1-rip-1]version 2 [R1-rip-1]network 192.168.1.0
[R2]rip 1 [R2-rip-1]version 2 [R2-rip-1]network 192.168.1.0 [R2-rip-1]network 10.0.0.0
[R3]rip 1 [R3-rip-1]version 2 [R3-rip-1]network 10.0.0.0 [R3-rip-1]network 172.16.0.0
[R4]rip 1 [R4-rip-1]version 2 [R4-rip-1]network 172.16.0.0
三、查看 路由表信息：
[R1]display rip 1 route
