Configure BFD for BGP

In a BGP core network, BFD provides rapid detection of communication failures in BGP fast-forwarding paths between internal BGP (iBGP)
and external BGP (eBGP) peers for faster network reconvergence. BFD for BGP is supported on 1GE, 10GE, port-channel, and VLAN
interfaces. BFD for BGP does not support IPv6 and the BGP multihop feature.
Prerequisites
Before configuring BFD for BGP, you must first configure the following settings:
1 Configure BGP on the routers that you want to interconnect, as described in
2 Enable fast fall-over for BGP neighbors to reduce convergence time (the neighbor fall-over command), as described in
Fast Fall-Over.
Establishing Sessions with BGP Neighbors
Before configuring BFD for BGP, you must first configure BGP on the routers that you want to interconnect.
For more information, refer to
For example, the following illustration shows a sample BFD configuration on Router 1 and Router 2 that use eBGP in a transit network to
interconnect AS1 and AS2. The eBGP routers exchange information with each other as well as with iBGP routers to maintain connectivity
and accessibility within each autonomous system.
