Configuring BFD for BGP

Network requirements
Switch A and Switch B are interconnected through a Layer 2 switch. BFD is enabled on the
connected interfaces. BGP is enabled on the switches that are reachable to each other at the
network layer.
When the link between Switch A and Switch B fails, BFD can quickly detect the failure and notify
BGP of the failure.
