Configuring OSPFv3 Stub Areas

Procedure

1. Run system-view

   The system view is displayed.

2. Run ospfv3 [ process-id ]

   The OSPFv3 view is displayed.

3. Run area area-id

   The OSPFv3 area view is displayed.

4. Run stub [ no-summary ]

   The area is configured as a stub area.

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.

6. Run commit

   The configuration is committed.
