Hi,
I will folloup on the other emails. Just catching up in reverse order. RDI
(Reverse defect indication) is what is used in RFC 6310 to indicate
failure in the rverse direction from the failure, and this document is
aligned with that. At the same time, RDI as Remote defect indication is
what is used for Ethernet CFM, so the attemot here is to call out
the acronyms used and in this case it is the same acronym that correspond
to two different terminologies, each with its own context identified.

Thanks,
Nabil
