What is BFD?

Bidirectional Forwarding Detection (BFD) is a network protocol used to detect faults between two forwarding engines. It provides low-overhead, short-duration detection of failures in the path between adjacent nodes, including interfaces, data links, and forwarding planes. It's commonly used to quickly detect link failures and reduce convergence times in routing protocols.
