(Optional) Configuring OSPFv3 to Filter LSAs in an Area

Context

After filtering criteria are set for the incoming or outgoing Type 3 LSAs (Inter-Area-Prefix LSAs) in an area, only the Type 3 LSAs that meet the criteria are received or advertised. This filters unnecessary LSAs, reduces the LSDB size, and increases network convergence.

This function is applicable only to the ABR.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run ospfv3 [ process-id ]

    The OSPFv3 process view is displayed.

  3. Run area area-id

    The OSPFv3 area view is displayed.

  4. Filter incoming or outgoing Type 3 LSAs in the area.

    • Run the filter { acl6-number | acl6-name acl6-name | ipv6-prefix ipv6-prefix-name | route-policy route-policy-name } import command to filter incoming Type 3 LSAs in the area.

    • Run the filter { acl6-number | acl6-name acl6-name | ipv6-prefix ipv6-prefix-name | route-policy route-policy-name } export command to filter outgoing Type 3 LSAs in the area.
