Dear John,
I think that MPLS-TP OAM CC/CV/RDI solution is based on BFD. It is not BFD in its entirety but is a subset with some aspects being specific for MPLS-TP and not part of RFC 5880.

Regards,
Greg

That statement is incorrect.  MPLS-TP uses BFD for CC/CV/RDI (http://datatracker.ietf.org/doc/draft-ietf-mpls-tp-cc-cv-rdi/)
