The Bidirectional Forwarding Detection (BFD) Protocol is a simple hello mechanism that
detects failures in a network. BFD works with a wide variety of network environments
and topologies. A pair of routing devices exchanges BFD packets. Hello packets are sent
at a specified, regular interval. A neighbor failure is detected when the routing device
stops receiving a reply after a specified interval. The BFD failure detection timers have
statement for that interface.
