OSPF常见故障处理

一、清除OSPF故障计数

reset OSPF counters(表示用来将OSPF计数器清零)

二、案例拓扑

1、接口down(查看启用OSPF各接口状态)

OSPF Process 1 with Router ID 1.1.1.1 OSPF error statistics

General packet errors: 0 : IP: received my own packet 0 : Bad packet 0 : Bad version 0 : Bad checksum 0 : Bad area id 0 : Drop on unnumbered interface 0 : Bad virtual link 0 : Bad authentication type 0 : Bad authentication key 0 : Packet too small 0 : Packet size > ip length 0 : Transmit error 1 : Interface down 0 : Unknown neighbor 0 : Bad net segment 0 : Extern option mismatch 0 : Router id confusion

2、双方area区域不一致(相连的设备OSPF区域要一致) [Huawei]display ospf error
