RFC 5880: Bidirectional Forwarding Detection (BFD)

Still current, but amended. Parts of this document are changed or extended by RFC 7419, RFC 7880, RFC 8562, RFC 9747. Read both.

In plain English — editorial summary, not part of the RFC

This document describes a protocol intended to detect faults in the bidirectional path between two forwarding engines, including interfaces, data link(s), and to the extent possible the forwarding engines themselves, with potentially very low latency. It operates independently of media, data protocols, and routing protocols. [STANDARDS-TRACK]
