配置rip动态路由协议实现全网互通
 
R1和R2的互联地址 192.168.0.0/24
R1和R3的互联地址 192.168.1.0/24
R2和R3的互联地址 192.168.2.0/24
R3和R4的互联地址 192.168.3.0/24
使用loopback接口模拟公司内部的客户端主机
R1的lo 0   192.168.10.1/24
R2的lo 0   192.168.20.1/24
R3的lo 0   192.168.30.1/24
R4的lo 0   192.168.40.1/24

标红的路由条目表示到目标网段有两条路径可走，跳数相同，因为RIP是以跳数作为度量值的
扩展RIPv2内容(修改lo 0 参数)
把 R1 lo 0 修改为10.10.10.1/24
把R2 lo 0 修改为10.10.20.1/24
把R3 lo 0 修改为10.10.30.1/24
把R4 lo 0 修改为10.10.40.1/24
然后每台路由宣告lo 0 网段network 10.0.0.0

R4
 R       10.0.0.0/8 [120/1] via 192.168.3.2, 00:00:14, FastEthernet0/0
 
 
R1 到10.10.20.1不通 10.10.30.1通  10.10.40.1不通
R2 到10.10.10.1通  10.10.30.1 通 10.10.40.1不通
R3到 10.10.10.1通 10.10.20.1 不通 10.10.40.1不通
R4 到10.10.10.1通 10.10.20.1不通 10.10.30.1通
解决办法：用RIPv2并且禁止路由汇总
