Configuring a Route Calculation Delay to Suppress Frequent LSA Flapping

Configuring a Route Calculation Delay to Suppress Frequent LSA Flapping

Context

Frequent OSPFv3 LSA flapping may lead to route flapping, adversely affecting services. To address this problem, run the maxage-lsa route-calculate-delay command to configure the device to delay route calculation when it receives a MaxAge Router LSA, which suppresses the frequent OSPFv3 LSA flapping that may occur.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run ospfv3 [ process-id ]

    The OSPFv3 view is displayed.

  3. Run maxage-lsa route-calculate-delay delay-interval

    A route calculation delay is configured and will be triggered when the device receives a MaxAge Router LSA.

    By default, the delay is 20s.

Verifying the Configuration

Run the display ospfv3 [ process-id ] statistics maxage-lsa command to display information about MaxAge Router LSAs.
