ospfv3 [ process-id ]
The OSPFv3 view is displayed.
Step 3 Run:
area area-id
The OSPFv3 area view is displayed.
Step 4 Run:
stub [ no-summary ]
The area is configured as a stub area.
Step 5 (Optional) Run:
default-cost cost
The cost of the default route sent to the stub area is set.
By default, the cost of the default route sent to the stub area is 1.
This command is configured on the ABR of the stub area only to set the cost of the default route
to be sent to the stub area. This command does not need to be configured on other switches in
the stub area.
The parameter no-summary takes effect only when the stub command is configured on the
ABR. If this parameter is configured, the ABR only sends the summary-LSA of a default route
to the stub area without originating other summary-LSAs. The stub area without AS-external-
LSAs or Summary-LSAs is called a totally stub area.

5.5.3 Configuring OSPFv3 Virtual Links
You can establish the logical connectivity between backbone areas and the non-backbone areas
that are not physically connected to the backbone area.
Context
After OSPFv3 areas are defined, OSPFv3 route update between non-backbone areas is
implemented through a backbone area. Then, OSPFv3 requires that all non-backbone areas
should maintain the connectivity with the backbone area and the backbone area should maintain
its own connectivity. In actual applications, this requirement may not be met because of some
restrictions. To solve this problem, you can configure OSPFv3 virtual links.
A virtual link must be configured at both ends of the link; otherwise, it does not take effect.
Do as follows on the switch that runs OSPFv3.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
