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.
In a stub area, all routers cannot receive external routes, and interfaces connected to the stub area must
be associated with the stub area.
Solution
1. Use the display ospfv3 peer command to display OSPFv3 neighbors.
2. Use the display ospfv3 interface command to display OSPFv3 interface information.
3. Use the display ospfv3 lsdb command to display LSDB information to check integrity.
4. Display information about area configuration using the display current-configuration
configuration command. If more than two areas are configured, at least one area is connected to
the backbone.
5. In a stub area, all routers are configured with the stub command.
6. If a virtual link is configured, use the display ospfv3 vlink command to check the neighbor state.
