BFD provides fast fault detection independent of media and routing protocols. To use this mechanism to detect link connectivity, devices at both ends must support this feature.

ATRUE

BFALSE

Show Suggested Answer

Suggested Answer: A

Comprehensive and Detailed Step-by-Step

Bidirectional Forwarding Detection (BFD):

BFD is a lightweight protocol that provides rapid fault detection on links independent of the underlying routing protocol or media.

Requirements for BFD:

Both devices at the endpoints of the link must support and configure BFD for it to operate.

If one device does not support BFD, the feature cannot be used for link detection.

Well, duh. If it's not supported on both ends, it's not gonna work. Although, I bet there's someone out there who would still try to force it just for fun.

Haha, I bet the engineers who came up with BFD were just sitting around, trying to one-up each other with 'how fast can we break this?'

True, true. If both ends don't support it, then it's a no-go. Might as well just use carrier pigeons instead.
