(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:

Adjust global BFD parameters if most RSVP interfaces on a node use the same BFD parameters.
Adjust BFD parameters on an RSVP interface if some RSVP interfaces require BFD parameters different from global BFD parameters.

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.
  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 { min-tx-interval configured for local device, min-rx-interval configured for remote device }
  
  Effective local interval at which BFD packets are received = MAX { min-tx-interval configured for remote device, min-rx-interval configured for local device }
  
  Effective local detection interval = MAX { min-tx-interval configured for remote device, min-rx-interval configured for local device } 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.
