Configuring P2MP Network Attributes

Configuring P2MP Network Attributes


  1. Disable OSPF from checking the network mask.
    1. Run system-view

      The system view is displayed.

    2. Run interface interface-type interface-number

      The interface view is displayed.

    3. Run ospf network-type p2mp

      The network type of the OSPF interface is configured.

      A P2MP network is forcibly changed from another type of network. For details, see Configuring Network Types for OSPF Interfaces.

    4. Run ospf p2mp-mask-ignore

      OSPF is disabled from checking the network mask on the P2MP network.

  2. Configure the router to filter the LSA packets to be sent.

    When multiple links exist between two routers, you can configure the local router to filter the LSA packets to be sent. This can reduce unnecessary LSA retransmission attempts and save bandwidth resources.

    1. Run quit

      Exit from the interface view.

    2. Run ospf [ process-id ]

      The OSPF process view is displayed.

    3. Run filter-lsa-out peer ip-address { all | { summary [ acl { acl-number | acl-name } ] | ase [ acl { acl-number | acl-name } ] | nssa [ acl { acl-number | acl-name } ] } * }

      The local router is configured to filter the LSA packets to be sent on the P2MP network.

      By default, the LSA packets to be sent are not filtered.
