TCP/IP 4.2.3 RIP单播更新

 

感谢上帝

上帝给了我一个非常勇敢乐观的母亲！

我真是个幸运的孩子

能有这样的母亲

我要做个勇敢乐观的孩子！

这才好呀

 

4.2.3 配置单播更新

根据前一小节 passive-interface 我们得知广播更新不会在被动接口发出，但是如果这个时候你想把信息传出去该怎么办

下面介绍一下单播更新

 

要求：路由器 Andy 和 Floyd 不进行 RIP 更新的交换，但是路由器 Andy 和 Floyd 都与路由器 Bea 交换 RIP 更新

 

注意： top 抓包 net 配置等文件都在附件里面

实验

TOP

配置

Andy#sh run | be rip
