注意这里的连通情况
一个通一个不通
注意代灰色背景的路由信息和后面的区别
PC1上的配置
上面是pc2的
Pc3的
Ping一下pc1 看看连通性
下面我们关闭自动汇总 看看与之前有什么区别
简单的说关闭自动汇总是为了解决不连续子网相互访问的问题

其他两台路由做同样的设置

ru3#
在看一下连同情况
ru3#ping 172.16.1.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 172.16.1.1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 7/7/8 ms
ru3#
被动接口：
由于内网的接口即f0/0接口连接主机，所以我们并不需要向这些接口发送路由更新信息，所以我们可以把这些接口设置为被动接口
被动接口的意思就是只接受rip更新而不向外发送路由更新信息
设置为被动接口，可以达到节省资源的目的
路由配置模式下
ru3#conf t
Enter configuration commands, one per line. End with CNTL/Z.
ru3(config)#route rip
ru3(config-router)#version 2
ru3(config-router)#pass
ru3(config-router)#passive-interface f0/0
ru3(config-router)#exit
ru3(config)#
其他两台路由器上做同样的配置
我们用sh ip pro 查看一下变化情况
