15、ingR1 的 lo1 口还是 R1pingR3的lol 口都不能Ping通,我换到R2继续PingR1的lol 口或是R3的lol 口都能全部 Ping 通,原因:因为使用了 RIP路由，RIP默认启用版本1是有类路由，当R1发现1.0.0.0和192.168.1.0 不是同类网段 ,会进行汇总 ,告诉 R2 自己汇总的路由 ,这样 R2 会知道 R1 有 1.0.0.0 和 192.168.1.0 两个网段 ,而 R3 也是同样原因告诉 R2 自己 1.0.0.0 和 192.168.2.0 两个网段 ,这时 候R2会知道R1和R3同时拥有1.0.0.0网段,所以无论是pingl.1.1.

16、1还是ping1.1.2.1会一个 包发向R1下一个包就会发向 R3,所以会出现一个包通，另一个包不通的结果.而 R1 无法拼通 1.1.2.1 是因为 ,R1 看自己的汇总路由发现这个地址就是在自己的网段里 , 解决方法，把 RIP修改为版本2，关闭自动汇总。如下图：在路由器 R1 上修改： ccna1(config)#router rip ccna1(config-router)#version 2 ccna1(config-router)#no auto-summary ccna1(config-router)# ccna1(config)#在路由器 R2 上的修改 ccna2#conf
