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 1. Enter system view. 2. Enter interface view. 3. Specify an NBMA or P2MP (unicast) neighbor and its DR priority. Command system-view interface interface-type interface-number ospfv3 peer ipv6-address [ cost value | dr-priority dr-priority ] [ instance instance-id ] Remarks N/A N/A By default, no link-local address is specified for the neighbor interface. Configuring OSPFv3 route control 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 falling into the specified network segment will not be advertised, reducing the LSDB size in other areas. To configure route summarization: Step 1. Enter system view. Command system-view Remarks 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. 304
