BFD

Bidirectional Forwarding Detection (BFD) is a network protocol that is used to detect faults between two forwarding engines connected by a link. It provides low-overhead detection of faults even on physical media that doesn't support failure detection of any kind, such as Ethernet, virtual circuits, tunnels and MPLS Label Switched Paths.
