3.4.2 Configuring an OSPFv3 Stub Area
Follow these steps to configure an OSPFv3 stub area:
To do... Use the command... Remarks
Enter system view
system-view
—
Enter OSPFv3 view ospfv3 [ process-id ]
—
Enter OSPFv3 area view
area area-id
—
Configure the area as a
stub area
stub [ no-summary ]
Required
Not configured by default
Configure the default
route cost of sending a
packet to the stub area
default-cost value
Optional
Defaults to 1
 Note:
z Configurations on the OSPFv3 routers attached to the same area must be
consistent. Otherwise, neighbor relationships cannot be established between
adjacent routers.
z You cannot delete an OSPFv3 area directly. Only when you remove all
configurations in area view and all interfaces attached to the area become down,
can the area be removed automatically.
z All routers attached to a stub area must be configured with the stub command. The
keyword no-summary is only available on the ABR.
z If you use the stub command with the keyword no-summary on an ABR, the ABR
distributes a default summary LSA into the area rather than generating an
AS-external-LSA or Inter-Area-Prefix-LSA. The stub area of this kind is also known
as totally stub area.
3.4.3 Configuring OSPFv3 Virtual Links
You can configure virtual links to maintain connectivity between non-backbone areas
and the backbone, or in the backbone itself.
Follow these steps to configure a virtual link:
