                            Configuration of
 Proactive Operations, Administration, and Maintenance (OAM) Functions
            for MPLS-Based Transport Networks Using RSVP-TE

Abstract

   This specification describes the configuration of proactive MPLS
   Transport Profile (MPLS-TP) Operations, Administration, and
   Maintenance (OAM) functions for a given Label Switched Path (LSP)
   using a set of TLVs that are carried by the GMPLS RSVP-TE protocol
   based on the OAM Configuration Framework for GMPLS RSVP-TE.
