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, 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 ospf vlink
command to check the neighbor state.
