6.4.2 Configuring OSPFv3 Stub Areas

A stub area is a special area in which ABRs do not flood the received AS external routes.
Therefore, the number of LSAs is greatly reduced.
Context
Perform the following steps on each router that runs OSPFv3 in the stub area:
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
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 routers 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.

6.4.3 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

implemented through a backbone area. Then, OSPFv3 requires that all non-backbone areas
