(Optional) Adjusting BFD Parameters

(Optional) Adjusting BFD Parameters

BFD parameters can be adjusted either globally or on a specific RSVP interface after BFD for RSVP is configured.

Context

Perform either of the following operations:

Procedure

  • Adjust global BFD parameters globally.

    Perform the following steps on the two RSVP neighboring nodes between which a Layer 2 device resides:

    1. Run system-view

      The system view is displayed.

    2. Run mpls

      The MPLS view is displayed.

    3. Run mpls rsvp-te bfd all-interfaces { min-tx-interval tx-interval | min-rx-interval rx-interval | detect-multiplier multiplier }*

      BFD parameters are set globally.

      NOTE:
      Parameters are described as follows:
      • tx-interval is the Desired Min Tx Interval (DMTI). It specifies the desired minimum interval at which BFD control packets are sent.

      • rx-interval is the Required Min Rx Interval (RMRI). It specifies the supported minimum interval at which BFD control packets are received.

      • multiplier is the BFD detection multiplier.

      BFD detection parameters that take effect on the local node may be different from the configured parameters:
      • Effective local interval at which BFD packets are sent = MAX { Configured local interval at which BFD packets are sent, Configured remote interval at which BFD packets are received }
      • Effective local interval at which BFD packets are received = MAX { Configured remote interval at which BFD packets are sent, Configured local interval at which BFD packets are received }
      • Effective local detection interval = Effective local interval at which BFD packets are received x Configured remote detection multiplier

    4. Run commit

      The configuration is committed.

  • Adjust BFD parameters on an RSVP interface.

    Perform the following steps on the two RSVP neighboring nodes between which a Layer 2 device resides:

    1. Run system-view

      The system view is displayed.

    2. Run interface interface-type interface-number

      The view of the RSVP-TE-enabled interface is displayed.

    3. Run mpls rsvp-te bfd { min-tx-interval tx-interval | min-rx-interval rx-interval | detect-multiplier multiplier }*

      BFD parameters on the RSVP interface are adjusted.

    4. Run commit

      The configuration is committed.
