路由间Rip V2协议的建立,认证以及触发更新

刚刚学了一下Rip协议的使用....现在与大家分享一下经验

我是用小凡摸拟器做出来的3台3640路由

接口情况如下:

Router1 S0/0 <----> Router2 S0/0
Router2 S0/1 <----> Router3 S0/1

R1 命令:

Router>en

Router(config)#ho r1
r1(config)#line co 0
r1(config-line)#logg sy
r1(config-line)#exec-timeout 0 0

这里我没有设置串口的时钟....因为我不知道它的作用是什么....还望各位大哥告知一
