Verify the configuration:

OSPFv3 packets between SecPath A, B and C are protected by IPsec.

Troubleshooting OSPFv3 configuration

No OSPFv3 neighbor relationship established

Symptom

No OSPF neighbor relationship can be established.

Analysis

If the physical link and lower protocol function properly, check 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.

Solution

1.

Display neighbor information using the display ospfv3 peer command.

2.

Display OSPFv3 interface information using the display ospfv3 interface command.

3.

Ping the neighbor router's IP address to check connectivity.

4.

Check OSPF timers. The dead interval on an interface must be at least four times the hello interval.

5.

On a broadcast network, at least one interface must have a DR priority higher than 0.
