一、OSPF建立邻居：
display ospf peer brief
二、验证了邻居表和路由表
display ospf peer brief
display ip routing-table
三、查看和更改loopback 0 的网络类型：
display ospf interface loopback 0
四、查看OSPF 路由的细分类型
display ospf routing
五、验证ASE类型的路由-引出类“路由宣告”方式：network/import-route
六、在R4上配置静态路由，然后import-route，在其他路由上查看
R4:
ip rout-static 100.1.1.0 255.255.255.0 null 0
ospf 1
import-route重分发 static
R3:
display ip routing-table
display ospf routing
