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:
Step Command
Remarks
1.
Enter system view.
system-view
N/A
2.
Enter interface view.
interface interface-type
interface-number
N/A
3.
Specify an NBMA or P2MP
(unicast) neighbor and its DR
priority.
ospfv3 peer ipv6-address [ cost
value | dr-priority dr-priority ]
[ instance instance-id ]
By default, no link-local
address is specified for the
neighbor interface.

Configuring OSPFv3 route control
393B
Configuration prerequisites
Before you configure OSPFv3 route control, complete the following tasks:
•
Configure IPv6 addresses for interfaces to ensure IPv6 connectivity between neighboring nodes.
•
Enable OSPFv3.

Configuring OSPFv3 route summarization
If contiguous network segments exist in an area, you can use the abr-summary command to summarize
them into one network segment on the ABR. The ABR will advertise only the summary route. Any LSA on
the specified network segment will not be advertised, reducing the LSDB size in other areas.
To configure route summarization:
Step Command
Remarks
1.
Enter system view.
system-view
N/A
2.
Enter OSPFv3 view.
ospfv3 [ process-id | vpn-instance
vpn-instance-name ] *
N/A
3.
Enter OSPFv3 area view. area area-id
N/A
4.
Configure route
summarization.
abr-summary ipv6-address prefix-length
[ not-advertise ] [ cost value ]
By default, route summarization is
not configured.
The abr-summary command takes
effect only on ABRs.
