    abstract =  {This document describes the mechanism to authenticate Bidirectional Forwarding Detection (BFD) protocol packets using Hashed Message Authentication Mode (HMAC) with the SHA-256, SHA-384, and SHA-512 algorithms. The described mechanism uses the Generic Cryptographic Authentication and Generic Meticulous Cryptographic Authentication sections to carry the authentication data. This document updates, but does not supercede, the cryptographic authentication mechanism specified in RFC 5880.},
