Suppress flapping peer

Status of OSPFv3 neighbor relationship flapping suppression:

  • enable: OSPFv3 neighbor relationship flapping suppression is enabled.

    • flapping-count: number of valid flapping_events

      If the interval between two successive neighbor status changes from Full to a non-Full state is shorter than detecting-interval, a valid flapping_event is recorded, and the flapping_count increases by 1. To change detecting-interval, run the ospfv3 suppress-flapping peer detecting-interval detecting-interval command.

    • threshold: flapping suppression threshold

      When the flapping_count reaches or exceeds threshold, flapping suppression takes effect. To configure the threshold, run the ospfv3 suppress-flapping peer threshold threshold command.

  • disable: OSPFv3 neighbor relationship flapping suppression is disabled. In this case, the following information is displayed, without flapping-count or threshold:
    Suppress flapping peer: disable
  • hold-down: OSPFv3 neighbor relationship flapping suppression works in Hold-down mode. In this case, an example of the displayed information is as follows:
    Suppress flapping peer: hold-down(start: 2016-01-02 09:58:41, remain-interval: 476 sec)
    • start: time when the flapping suppression started
    • remain-interval: remaining time of the flapping suppression
    NOTE:
    In the flapping suppression state, remain-interval is reset each time when the device detects a valid neighbor flapping event.
  • hold-max-cost: OSPFv3 neighbor relationship flapping suppression works in Hold-max-cost mode. In this case, an example of the displayed information is as follows:
    Suppress flapping peer: hold-max-cost(start: 2016-01-02 09:58:41, remain-interval: 476 sec)
