4、实验步骤：
（1）配置Router 1：
Router>enable //进入特权模式
Router#configure terminal //进入配置模式
Enter configuration commands, one per line. End with CNTL/Z. Router(config)#interface FastEthernet0/0 //配置端口 Router(config-if)#ip address 172.16.0.1 255.255.255.0
Router(config-if)#no shutdown
%LINK-5-CHANGED: Interface FastEthernet0/0, changed state to up

（5）配置校验、诊断（鉴于篇幅，以下命令均在router 6 上调试）
show ip protocol 查看路由器中所启用的路由计算协议：
show ip ospf：
show ip ospf neighbor
show ip ospf database
