拓扑环境

IP地址配置如下：
PC1=192.168.1.1/24
PC2=172.16.0.1/16
AR3_GI0/0/1=192.168.1.254/24
AR3_GI0/0/0=10.0.0.1/8
AR3_LO0=1.1.1.1/0
AR5_GI0/0/1=172.16.0.254/16
AR5_GI0/0/0=10.0.0.2/8
AR5_LO0=2.2.2.2/0

OSPF配置如下：

配置验证：
使用display ospf peer brief 看状态是FULL
使用display ip routing-table 查看路由表，有对端的路由信息
PC1 PING PC2可以ping通。
