(Optional) Adjusting BFD Parameters

(Optional) Adjusting BFD Parameters

PIM BFD parameters include the minimum interval for sending and receiving PIM BFD packets and the local detection multiplier. PIM BFD parameters can be adjusted as needed.


Perform the following steps on PIM routers that set up neighbor relationships:


  1. Run system-view

    The system view is displayed.

  2. Run interface interface-type interface-number

    The interface view is displayed.

  3. Run pim bfd { min-tx-interval tx-value | min-rx-interval rx-value | detect-multiplier multiplier-value } *

    PIM BFD parameters are adjusted.

    If BFD parameters configured for other protocols are the same as those configured for PIM, the configurations of the PIM BFD parameters are affected.

    The two ends negotiate the actual sending interval and receiving interval, and detection period of PIM IPv6 BFD packets based on the following negotiation mechanism:
    • Actual sending interval and receiving interval of PIM BFD packets:
      • Actual sending interval = max (local min-tx-interval, remote min-rx-interval)
      • Actual receiving interval = max (remote min-tx-interval, local min-rx-interval)
    • Actual detection period = remote detect-multiplier x max (remote min-tx-interval, local min-rx-interval)

    BFD parameters can be configured on both the receive and transmit ends, and the configurations on the two ends are both effective.
