For Network devices (routers, switches, etc) that are not directly connected to each other, cannot detect failures that may occur on the path between them, Bi-directional forwarding detection - BFD can support network devices to rapidly detect remote failures at milliseconds interval by being bounded to network protocols to rapidly notify them about discovered failures to minimise packet drops.
