Setting an OSPF Packet Retransmission Limit

Setting an OSPF Packet Retransmission Limit


After an OSPF switch sends DD, LSU, or LSR packets but does not receive any LSAck packet within a specified time, the switch retransmits the packet. If the number of packet retransmissions reaches a specified limit, the switch tears down the adjacency relationship with its neighbor.


  1. Run system-view

    The system view is displayed.

  2. Run ospf [ process-id ]

    The OSPF process view is displayed.

  3. Run retransmission-limit [ max-number ]

    An OSPF packet retransmission limit is set.

    By default, the OSPF packet retransmission limit is not set. If an OSPF packet retransmission limit is set, the default max-number is 30.
