Prerequisites

Enable IPv6 packet forwarding
Configure OSPFv3 basic functions

Configuring an OSPFv3 Stub Area

Follow these steps to configure an OSPFv3 stub area:
To do...
Enter system view
Enter OSPFv3 view
Enter OSPFv3 area view
Configure the area as a stub area
Specify a cost for the default route
advertised to the stub area
You cannot remove 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.
All the routers attached to a stub area must be configured with the stub command. The keyword
no-summary is only available on the ABR of the stub area.
If you use the stub command with the keyword no-summary on an ABR, the ABR advertises a
default route in an Inter-Area-Prefix-LSA into the stub area. No AS-external-LSA,
Inter-Area-Prefix-LSA or Inter-Area-Router-LSA is advertised in the area. The stub area of this
kind is also known as a totally stub area.

Configuring an OSPFv3 Virtual Link

You can configure a virtual link to maintain connectivity between a non-backbone area and the
backbone, or in the backbone itself.
Follow these steps to configure a virtual link:
To do...
Enter system view
Enter OSPFv3 view
Enter OSPFv3 area view
Use the command...
system-view
ospfv3 [ process-id ]
area area-id
stub [ no-summary ]
default-cost value
Use the command...
system-view
ospfv3 [ process-id ]
area area-id
