1、ENSP 添加三个AR220路由，分别命名为R1/R2/R3R1地址分配：G0/0/0 ip:1.0.0.1 掩码:255.0.0.0G0/0/1 ip:2.0.0.1 掩码:255.0.0.0R2地址分配：G0/0/0 ip:1.0.0.2 掩码:255.0.0.0G0/0/1 ip:2.0.0.2 掩码:255.0.0.0R3地址分配：G0/0/0 ip:3.0.0.1 掩码:255.0.0.0G0/0/1 ip:4.0.0.1 掩码:255.0.0.0PC1:3.0.0.2 255.0.0.0PC2:4.0.0.2 255.0.0.0
4、查看OSPF 路由表命令：dis ospf ro
