Not sure if this has changed, but the last time I looked into it, Micro
BFD's for LAG's was only supported and functional on point-to-point
Ethernet links.

LAG - Micro BFD (RFC7130) provides per constituent livability. MLAG is much
more complicated (there’s a proposal in IETF but not progressing), so LACP is
pretty much the only option.
ECMP could use old/good single hop BFD per pair.
Practically - if you introduce enough flows with one of the hash
Hello all.
Over time, we've run into occurrences of both bugs and human error, both in our
own gear and in our partner networks' gear, specifically affecting multi-path
forwarding, at pretty much all layers: Multi-chassis LAG, ECMP, and BGP MP.
