OSPF案例分析之如何得到正常的OSPF路由

内容摘要:日前,笔者在工作中发现一个问题,即无法得到正常的OSPF路由。笔者现将OSPF协议排错的过程写下来,希望能与更多的朋友共享。
router-id 197.7.1.2
log-adjacency-changes
network 100.1.0.2 0.0.0.0 area 0
network 222.222.222.1 0.0.0.0 area 0
neighbor 100.1.0.1 cost 200
故障现象如下:
在RouterA和RouterB上查看路由表,发现相互之间并没有学习到OSPF路由。
2、显示OSPF信息
分别在两台路由器上查看邻居状态,显示如下:
RouterA#show ip ospf neighbor
Neighbor ID Pri State Dead Time Address Interface
197.7.1.2 0 FULL/ - 00:01:38 100.1.0.2 Serial1/0
RouterA#show ip ospf neighbor
Neighbor ID Pri State Dead Time Address Interface
197.7.1.1 1 FULL/BDR 00:01:54 100.1.0.1 Serial1/0
然后分别察看路由表,有下列显示:
RouterA#show ip route
100.0.0.0/16 is subnetted, 1 subnets
C 100.1.0.0 is directly connected, Serial1/0
197.7.1.0/32 is subnetted, 1 subnets
C 197.7.1.1 is directly connected, Loopback0
111.0.0.0/24 is subnetted, 1 subnets
C 111.111.111.0 is directly connected, FastEthernet0/0
RouterB#show ip route
C 222.222.222.0/24 is directly connected, FastEthernet0/0
100.0.0.0/16 is subnetted, 1 subnets
C 100.1.0.0 is directly connected, Serial1/0
接下来在来查看两台路由器的接口状态如下:
RouterA#show ip ospf interface
FastEthernet0/0 is up, line protocol is up
