Configuring the SPF Timer

Configuring the SPF Timer


When the OSPFv3 link state database (LSDB) changes, SPF calculation needs to be performed again. A shorter SPF calculation interval can increase the network convergence speed, but also occupies more resources. If the network changes frequently, the bandwidth may be used up. A longer SPF calculation interval occupies less resources, which prevents the bandwidth from being used up due to frequent network changes. However, the network convergence speed becomes slower in this scenario. Set the interval based on the actual network.

Do as follows on the router that runs OSPFv3.


  • Configure an SPF normal timer.
    1. Run system-view

      The system view is displayed.

    2. Run ospfv3 [ process-id ]

      The OSPFv3 view is displayed.

    3. Run spf timers delay-interval hold-interval

      An SPF normal timer is configured.

  • Configure an SPF intelligent timer.
    1. Run system-view

      The system view is displayed.

    2. Run ospfv3 [ process-id ]

      The OSPFv3 view is displayed.

    3. Run spf-schedule-interval { delay-interval hold-interval | intelligent-timer max-interval start-interval hold-interval-1 }

      An SPF intelligent timer is configured.

      An SPF normal timer and an SPF intelligent timer are mutually exclusive.
