fast hello packet? are you kidding me? IGP hello packet can be adjusted to seconds, but BFD can be adjusted to subsec, so BFD is the boss here for failure detection I think the other correct answer is UDLD , this is for detecting failure path in unidirection either tx or rx in Physical level, not IP level like BFD
