Configure BFD Sessions for BGP

  1. Access global configuration mode.
    device# configure terminal
  2. Access BGP configuration mode.
    device(config)# router bgp
  3. Specify the transmit time, the receive time, and the number of consecutive control packets that must be missed before the connection to a peer is considered non-operational.
    device(config-bgp-router)# bfd interval 140 min-rx 125 multiplier 44
    The above example specifies a transmit interval of 140 ms, the min-rx keyword followed by a receive interval of 125 ms, and the multiplier value of 44, which indicates that 44 consecutive packets must be missed before the connection to the peer is considered non-operational.
  4. Specify the interval after which BGP routes are withdrawn after a BFD session is declared down.
    device(config-bgp-router)# bfd holdover-interval 15
    The above example specifies a holdover interval of 15 seconds.
