实验11：RIPv1 基本配置
1.
实验目的
通过本实验可以掌握：
（1）在路由器上启动RIPv1 路由进程
（2）启用参与路由协议的接口，并且通告网络
（3）理解路由表的含义
（4）查看和调试RIPv1 路由协议相关信息
2.
拓扑结构
实验拓扑如图 所示。

实验步骤
1）步骤1：配置路由器R0

r0#conf t
Enter configuration commands, one per line. End with CNTL/Z.
r0(config)#router rip

r0(config-router)#net

r0(config-router)#net 192.168.12.0
r0(config-router)#do ping 192.168.34.2
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.34.2, timeout is 2 seconds:

R

.0/8 [120/3] via 192.168.12.2, 00:00:26, Serial
1/1/0
C 192.168.12.0/24 is directly connected, Serial
1/1/0
R 192.168.23.0/24 [120/1] via 192.168.12.2, 00:00:26, Serial
1/1/0
R 192.168.34.0/24 [120/2] via 192.168.12.2, 00:00:26, Serial
1/1/0
以上输出表明路由器R1 学到了3 条RIP 路由，其中路由条目“R
4.0.0
.0/8 [120/3]
via 192.168.12.2, 00:00:26, Serial1/1/0”的含义如下：
① R：路由条目是通过RIP 路由协议学习来的；
②
4.0.0
.0/8：目的网络；
③ 120：RIP 路由协议的默认管理距离；
④ 3: 度量值，从路由器R1 到达网络
4.0.0
.0/8 的度量值为3 跳；
⑤ 192.168.12.2：下一跳地址；
⑥ 00:00:26：距离下一次更新还有4（30-26）秒；
⑦ Serial1/1/0：接收该路由条目的本路由器的接口。
同时通过该路由条目的掩码长度可以看到，RIPv1 确实不传递子网信息。
