Configuring an OSPFv3 Stub Area

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.

   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. It does not generate other summary-LSAs, such as AS-external-LSAs or Summary-LSAs. This area is called a totally stub area.

5. (Optional) Run default-cost cost

   The cost of the default route sent to the stub area is set.

   By default, this cost is 1.

   Step 5 is performed only on the ABR. It is not necessary to perform this step on other switches in the stub area.
