Usage Guidelines

Usage Scenario

To fast detect link faults, run the bfd command in the system view to enable global BFD.

Precautions

BFD must be enabled globally before BFD parameters are configured.

Running the undo bfd command in the system view may affect services associated with BFD and deletes all BFD sessions on the device. To restore the BFD function, you have to re-configure BFD sessions.
