Configuring an Intelligent Timer for Generating LSAs

Configuring an Intelligent Timer for Generating LSAs

Context

Setting the millisecond-level interval for generating the same LSA speeds up network convergence. When a network becomes unstable, reduce the interval for generating the same LSA by using an intelligent timer.

Do as follows on the router that runs OSPFv3.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run ospfv3 [ process-id ]

    The OSPFv3 view is displayed.

  3. Run lsa-originate-interval intelligent-timer max-interval start-interval hold-interval

    The interval for updating OSPFv3 LSAs by using an SPF intelligent timer is set.

    • max-interval specifies the maximum interval for updating LSAs. The value ranges from 1 to 10000, in milliseconds.
    • start-interval specifies the initial interval for updating LSAs. The value ranges from 0 to 1000, in milliseconds.
    • hold-interval specifies the hold interval for updating LSAs. The value ranges from 1 to 5000, in milliseconds.

    By default, the maximum interval for updating LSAs is 5000 ms, the initial interval for updating LSAs is 500 ms, the hold interval for updating LSAs is 1000 ms.

  4. (Optional) Run:

    lsa-originate-interval suppress-flapping suppress-interval [ threshold count ]

    The maximum OSPFv3 LSA suppression period is configured.

    If frequent OSPFv3 LSA flapping occurs, the larger value between lsa-originate-interval suppress-flapping and lsa-originate-interval is used to suppress LSA flapping.
