Follow these guidelines when you change the network type of an OSPFv3 interface:
•
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, enable OSPFv3.

3. Configure a network type
for the OSPFv3 interface.

By default, the network type of an
OSPFv3 interface is broadcast.
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. For NBMA interfaces, you can also specify DR priorities for neighbors.
To configure an NBMA or P2MP (unicast) neighbor and its DR priority:

1. Enter system view.

2. Enter interface view.

3. Specify an NBMA or P2MP
(unicast) neighbor and its DR
priority.

By default, no link-local
address is specified for the
neighbor interface.
Configuring OSPFv3 route control
Configuration prerequisites
Before you configure OSPFv3 route control, perform the following tasks:
•
Configure IPv6 addresses for interfaces to ensure IPv6 connectivity between neighboring
nodes.
•
Enable OSPFv3.
