34.2.3 Configure BGP4 Peer Monitoring [SL-L3A]

The following shows a sample BFD monitoring configuration for BGP4 peers.

Points to note

Specify BFD for BGP4 monitoring when configuring peering.

If BFD is used to monitor BGP4 peers that do not use the address of a directly-connected interface, set IP address and configuration command multihop for the loopback interface.
