查看路由器运行的OSPF信息:display ospf brief
查看运行的OSPF邻居情况:display ospf peer brief
查看路由器的OSPF数据库信息:display ospf lsdb
查看一类LSA信息:display ospf lsdb router self-originate
查看二类LSA信息:display ospf lsdb network self-originate
重置OSPF进程:在用户视图下:reset ospf process 会重新选举DR和BDR
查看OSPF进程在loopback0下的状态信息:display ospf interface loopback 0 verbose
修改loopback 0的网络类型:
[R1]interface loopback 0
[R1-LoopBack0]ospf network-type broadcast/p2p
修改OSPF接口代价值:
[R1]interface g0/0/0
[R1-GigabitEthernet0/0/0]ospf cost **
配置静默接口:
[R1]ospf 1
[R1-ospf-1]silent-interface g0/0/0
静默接口不接收和发送hello报文,且loopback0接口配置为静默接口不会影响ospf的发布
