(Optional) Adjusting BGP BFD Parameters

Procedure

1. Run system-view

   The system view is displayed.

2. Run bfd

   The BFD view is displayed.

3. Run mpls ping interval interval

   The interval at which LSP ping packets are sent is set.

4. Run quit

   Return to the system view.

5. Run mpls

   The MPLS view is displayed.

6. Run mpls bgp bfd { min-tx-interval interval | min-rx-interval interval | detect-multiplier multiplier }*

   BGP BFD time parameters are set.

   Effective BFD time parameters are calculated using the following formulas:

   • Effective local interval at which BFD packets are sent = MAX { Locally configured minimum interval at which BFD packets are sent, Remotely configured minimum interval at which BFD packets are received }

   • Effective local interval at which BFD packets are received = MAX { Remotely configured minimum interval at which BFD packets are sent, Locally configured minimum interval at which BFD packets are received }

   • Local BFD detection period = Effective local interval at which BFD packets are received x Remotely configured BFD detection multiplier

   The egress has the fixed minimum interval at which BGP BFD packets are sent, the fixed minimum interval at which BGP BFD packets are received, and the detection multiplier of 3. You can only change the time parameters on the ingress so that the BFD time parameters can be updated on both the ingress and egress.

7. Run commit

   The configuration is committed.
