Configuring OSPFv3 Routing Information Management 447
Prerequisites ■ Enable IPv6 packet forwarding
■ Configure OSPFv3 basic functions
Configuring an OSPFv3
Stub Area
Follow these steps to configure an OSPFv3 stub area:
n
■ Configurations on the OSPFv3 routers attached to the same area must be
consistent. Otherwise, neighbor relationships cannot be established between
adjacent 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.
■ 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.
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:
n
Both ends of a virtual link are ABRs that are configured with the vlink-peer
command.
