Configuring OSPFv3 Route Aggregation

Configuring OSPFv3 Route Aggregation

Context

If multiple continuous network segments exist in an area, use the abr-summary command to summarize them into one network segment. The ABR then only sends a summary LSA, and LSAs that belongs to the summarization network segment are not separately transmitted.

Procedure

  • Configure route summarization on an ABR.

    Perform the following operations on the ABR that runs OSPFv3.

    1. Run system-view

      The system view is displayed.

    2. Run ospfv3 [ process-id ]

      The OSPFv3 view is displayed.

    3. Run area area-id

      The OSPFv3 area view is displayed.

    4. Run abr-summary ipv6-address prefix-length [ cost cost | not-advertise ] *

      Route summarization is configured in the OSPFv3 area.

      cost cost sets a cost for a summarized route. By default, this cost is the maximum cost of the summarized routes. The value ranges from 1 to 16777214.

      If not-advertise is set, no routing information for the network segment is advertised.
