Configuring OSPFv3
Area Parameters

Prerequisites

Configuring an OSPFv3
Stub Area
To do...
Enable OSPFv3 on the
interface
n
Configure an OSPFv3 process ID when enabling OSPFv3. The process ID takes
■
effect locally, without affecting packet exchange between routers.
When configuring a router ID, make sure each router has a unique ID. If a
■
router runs multiple OSPFv3 processes, you need to specify a router ID for each
process.
You need to specify a router ID manually, which is necessary to make OSPFv3
■
work.
The stub area and virtual link support of OSPFv3 has the same principle and
application environments with OSPFv2.
Splitting an OSPFv3 AS into multiple areas reduces the number of LSAs on
networks and extends OSPFv3 application. For those non-backbone areas residing
on the AS boundary, you can configure them as Stub areas to further reduce the
size of routing tables on routers in these areas and the number of LSAs.
Non-backbone areas exchange routing information via the backbone area.
Therefore, the backbone and non-backbone areas, including the backbone itself
must maintain connectivity. In practice, necessary physical links may not be
available for connectivity. You can configure virtual links to address it.
Enable IPv6 packet forwarding
■
Configure OSPFv3 basic functions
■
To configure an OSPFv3 stub area, use the following commands:
To do...
Enter system view
Enter OSPFv3 view
Enter OSPFv3 area view
Configure the area as a stub
area
Configure the default route
cost of sending a packet to
the stub area
n
Configurations on the routers attached to the same area should be compatible;
■
otherwise, no neighbor relationships may be established between the routers.
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.
All routers attached to a stub area must be configured with the stub
■
command. The keyword no-summary is only available on the ABR.
