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 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
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.
