简单的路由重分布实验（rip和ospf重分布）
1、网络拓扑，R1，R2，R3相连
Router1 S0/0 <----> Router2 S0/0
Router2 S0/1 <----> Router3 S0/1
2、具体配置
R1配置
R1>en
R1#config te
R1#config terminal
R1(config)#interface serial 0/0

R1(config-if)#clock rate 64000
R1(config-if)#no shut
R1(config-if)#exit
R1(config)#interface loopback 0
R1(config-if)#ip add 10.0.0.1 255.255.255.255 //R1环回口接口地址
