Usage Guidelines

Usage Scenario

When a BFD session flaps, the WTR time prevents frequent active/standby switchovers of the application associated with the BFD session.

Precautions

  • If the WTR time is set, the system reports the BFD session Up event to the upper-layer application only after the WTR timer expires. Other status change events are reported immediately, which are not affected by the WTR time.

  • Both ends must use the same WTR time. Otherwise, when the session status changes at one end, applications at both ends detect different BFD session status.

Example

# Set the WTR time of a BFD session to 10 minutes.
