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.
Configuration prerequisites
Before you configure OSPFv3 network types, complete the following tasks:
• Configure IPv6 functions.
• Configure OSPFv3 basic functions.

Optional.
The network type of an interface
depends on the media type of the
interface.
Configuring an NBMA or P2MP neighbor
For NBMA and P2MP interfaces (only when in unicast mode), you must specify the link-local IP addresses
of their neighbors because these interfaces cannot find neighbors through broadcasting hello packets.
You can also specify DR priorities for neighbors.
To configure an NBMA or P2MP (unicast) neighbor and its DR priority:
