Configure a virtual link

Required
z Both ends of a virtual link are ABRs that must be configured with the vlink-peer command.
z Do not configure virtual links in the areas of a GR-capable process.
Configuring OSPFv3 Network Types
OSPFv3 classifies networks into four types upon the link layer protocol:
By default, the default OSPFv3 interface network types vary with the link layer protocols of the
interfaces:
z When the link layer protocol is PPP, OSPFv3 considers the network type as P2P by default.
z 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 as needed. For example:
z An NBMA network must be fully connected. That is, any two routers in the network must be
directly reachable to each other through a virtual circuit. In the event no such direct link is
available, you need to change the network type through a command.
z If direct connections are not available between some routers in an NBMA network, the type of
interfaces associated should be configured as P2MP, or as P2P for interfaces with only one
neighbor.
Prerequisites
Before configuring OSPFv3 network types, you have configured:
z IPv6 functions
z OSPFv3 basic functions
