                 Configuration of Proactive Operations,
     Administration, and Maintenance (OAM) Functions for MPLS-Based
        Transport Networks Using Label Switched Path (LSP) Ping

Abstract

   This specification describes the configuration of proactive 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 LSP Ping protocol.
