Anyone already done it a configuration BGPv4 with BFD fail-over ?
Because i have make this configuration and BFD don't play, no neighbors visible.
Must Be put on a specific configuration interface in addition to router BGP with "bfd-enable" and neighbor X.X.X.X fail-over bfd-enable ?

Enabling BFD for BGP4 globally
By default, BFD for BGP4 is disabled and can be first enabled globally and then on each peer. To enable BFD for BGP4 globally, enter commands such as the following.
NetIron# router bgp
For a single hop EBGP session, the BFD parameters configured under interface will be used because the BFD session for single hop is also shared with other applications. To create a BFD
session for a single hop BGP4 session, you must have BFD enabled and the timers configured for the interface on which single hop BGP4 peering is established.
To configure a multi hop EBGP or IBGP session, enter a command such as the following.
NetIron(config)# router bgp
NetIron(config-bgp)# bfd min-tx 500 min-rx 500 multiplier 5
Enabling BFD for a specific BGP4 peer
To enable BFD for BGP4 for a specific neighbor or peer, enter a command such as the following
NetIron(config-bgp)# neighbor 22.214.171.124 fail-over bfd-enable
Mark sure you timers match on both ends
Enabling BFD timers for a specific BGP4 peer
To enable BFD timers for a specific neighbor or peer for BGP4, you must first configure the bfd timers, and set the holdover interval by entering commands such as the following.
NetIron(config-bgp)# neighbor 126.96.36.199 bfd min-tx 500 min-rx 500 multiplier 5
NetIron(config-bgp)# bfd holdover-interval 20
