Configuring an OSPFv3 stub area
Follow these guidelines when you configure an OSPFv3 stub area:
• You cannot remove an OSPFv3 area directly. The area can be removed only when you remove all
configurations in area view and all interfaces attached to the area become down.
• 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-Router-LSA, or other Inter-Area-Prefix-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.

Both ends of a virtual link are ABRs that must be configured with the vlink-peer command.
