Technical Summary
This document clarifies the procedures for establishing, maintaining
and removing multiple, concurrent BFD sessions for a given <MPLS LSP,
FEC> described in RFC5884.
Working Group Summary
This document received good discussion among key contributors
in the BFD Working Group. Nothing controversial was discussed, the
clarifications are considered sound practice.
Document Quality
RFC 5884 is implemented by a number of vendors that support MPLS and BFD
to verify those MPLS LSPs. This clarifications document was motivated
by some ambiguities in that RFC which were noted as implementors were
attempting to implement some of the edge cases. Implementations are
expected to pick up the changes in this document soon if they are not
otherwise implemented already.
This document does not impact backward compatibility.
