CCNA第四天实验（rip，eigrp，ospf）

动态路由协议

rip 路由消息协议

(config)#Router rip(config)#version 2(config)#no auto-summary //不进行自动汇总(config)#network 网络号

eigrp 思科私有协议

(config)#router eigrp 自制系统号(config)#no auto-summary(config)#network 网络号 反掩码

连接几个网络，宣告几个网络

ospf 开放的最短路径优先协议

(config)#router ospf 进程号(config)#network 网号号反码 area 区域号

动态路由实验

建立一个简单拓扑用于实验
