Troubleshooting OSPF configuration
667BNo OSPF neighbor relationship established
1452BSymptom
No OSPF neighbor relationship can be established.
1453BAnalysis
If the physical link and lower layer protocols work well, verify OSPF parameters configured on interfaces.
Two neighbors must have the same parameters, such as the area ID, network segment, and mask (a P2P
or virtual link may have different network segments and masks).
