Configuring Association Between BFD and a Card

Configuring Association Between BFD and a Card


After VRRP is enabled on a switch used as the aggregation device and gateway, VRRP Advertisement packets are forwarded through a Layer 2 switch at the access layer. To improve the VRRP switching performance, associate VRRP with BFD. In this case, BFD packets are also forwarded through a Layer 2 switch at the access layer.

If uplink outbound interfaces of a VRRP group are located on the same card, the card reset may cause a failure to forward user traffic because there is no outbound interface. In this situation, a VRRP active/standby switchover must be performed. The link monitored by BFD is normal and the BFD session does not go Down, so the millisecond-level switching performance cannot be ensured. After a BFD session is associated with a card and the card is set, the BFD session immediately goes Down, triggering the VRRP active/standby switchover. The switching performance is therefore improved.


The device supports this command only when the MPU is ET1D2MPUA000 or ET1D2MPUDC00.


  1. Run system-view

    The system view is displayed.

  2. Run bfd-track slot slot-id [ interval second-time ]

    BFD is associated with a card.

    By default, BFD is not associated with a card.
