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.
IMPORTANT:
• Both ends of a virtual link are ABRs that must be configured with the vlink-peer command.
• Do not configure virtual links in the areas of a GR-capable process.
To configure a virtual link:
Step
Enter system view.

Configuring OSPFv3 network types

OSPFv3 classifies networks into the following types by the link layer protocol:
By default, the OSPFv3 interface network types vary with the link layer protocols of the interfaces:
•
When the link layer protocol is PPP, OSPFv3 considers the network type as P2P by default.
•
When the link layer protocol is Ethernet, OSPFv3 considers the network type as broadcast by
default.
You can change the network type of an OSPFv3 interface in the following cases:
•
An NBMA network must be fully connected. Any two routers in the network must be directly
reachable to each other through a virtual circuit. If no such direct link is available, you must
change the network type through a command.
•
If direct connections are not available between some routers in an NBMA network, the type of
interfaces associated must be configured as P2MP, or as P2P for interfaces with only one
neighbor.
