Enable BFD at the BGP Application Level

BFD for IPv6 interfaces is a demonstration feature on some products. For more information about feature support, see Fabric Engine and VOSS Feature Support Matrix.

About this task

BFD supports internal Border Gateway Protocol (iBGP) and external Border Gateway Protocol (eBGP) on IPv4 interfaces. You configure BFD on a VRF instance the same way you configure the GlobalRouter, except that you must use VRF Router Configuration mode and the prefix ip bgp. BFD does not support BGPv6 for VRF on IPv6 interfaces.

Note

Note

Enabling BFD at the BGP application level does not establish a BFD session. To establish a BFD session, you must enable BFD globally and at the interface level.

Procedure

  1. Enter BGP Router Configuration mode:

    enable

    configure terminal

    router bgp

  2. Enable BFD for the BGP protocol:

    neighbor WORD<0-1536> fall-over bfd

Example

Switch:1>enable
Switch:1#configure terminal
Enter configuration commands, one per line.  End with CNTL/Z.
Switch:1(config)#router bgp
Switch:1(router-bgp)#neighbor 192.0.2.15 fall-over bfd
