Setting the OSPF Packet Retransmission Limit

Setting the OSPF Packet Retransmission Limit


After an OSPF switch sends a DD packet, an LSU packet, or an LSR packet, if it does not receive an LSAck packet within a specified period, it retransmits the packet. After the number of packet retransmissions reaches a specified limit, the OSPF switch tears down the adjacency relationship.


  1. Run system-view

    The system view is displayed.

  2. Run ospf [ process-id ]

    The OSPF view is displayed.

  3. Run retransmission-limit [ max-number ]

    The OSPF packet retransmission limit is set.

    By default, no limit is set for OSPF packet retransmissions. The default maximum number of packet retransmissions is 30.

  4. Run commit

    The configuration is committed.
