No OSPFv3 neighbor relationship established
Symptom
No OSPF neighbor relationship can be established.
Analysis
If the physical link and lower protocol function properly, verify OSPF parameters configured on interfaces. The two neighboring interfaces must have the same parameters, such as the area ID, network segment and mask, and network type. If the network type is broadcast, at least one interface must have a DR priority higher than 0.
Process steps
Use the display ospfv3 peer command to display neighbor information.
Use the display ospfv3 interface command to display OSPFv3 interface information.
Ping the neighbor router's IP address to verify connectivity.
Verify OSPF timers. The dead interval on an interface must be at least four times the hello interval.
On a broadcast network, at least one interface must have a DR priority higher than 0.
