OSPFv3 packets between Switches 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
Use the display ospfv3 peer command to display neighbor information.
1.
Use the display ospfv3 interface command to display OSPFv3 interface information.
2.
Ping the neighbor router's IP address to verify connectivity.
3.
Verify OSPF timers. The dead interval on an interface must be at least four times the hello
4.
interval.
On a broadcast network, at least one interface must have a DR priority higher than 0.
5.

Incorrect routing information

Symptom
OSPFv3 cannot find routes to other areas.
Analysis
The backbone area must maintain connectivity to all other areas. If a router connects to more than
one area, at least one area must be connected to the backbone. The backbone cannot be configured
as a stub area.
