Got an off-list hint on what to do. Which got me going again.
BFD_MP_DOWNLOAD_NO_LC <-- Meant I forgot to turn on BFD for the
linecard.
Configured "bfd multipath include location ?/?/CPU?" did it.
Realised upon receiving hint. I had overlooked a section in the Cisco
configuration guide. Mentioning turning on BFD-per-linecard-basis
is mandatory. And BFD will not work if this step is forgotten. Yes,
I was able to configure everything. Just, it would not work and
got stuck with the previous error-code. Which I was challenged throwing
search engine magic after, finding useful information on.
