         RSVP-TE Extensions to Exchange MPLS-TP LSP Identifiers

Abstract

   The MPLS Transport Profile (MPLS-TP) identifiers document [RFC6370]
   specifies an initial set of identifiers, such as local assigned
   tunnel number and Global_ID, which can be used to form Maintenance
   Entity Point Identifier (MEP_ID).  As to some Operation,
   Administration and Maintenance (OAM) functions, such as Connectivity
   Verification (CV) [RFC6428], source MEP_ID must be inserted in the
   OAM packets, so that the peer endpoint can compare the received and
   expected MEP_IDs to judge whether there is a mismatch [RFC6371],
   which means that the two MEP nodes need to pre-store each other's
   MEP_IDs.

   This document defines the signaling extensions to exchange the Label
   Switched Path (LSP) identifiers.

1.  Introduction

   The MPLS Transport Profile (MPLS-TP) identifiers document [RFC6370]
   specifies a initial set of identifiers, such as local assigned tunnel
   number (Tunnel_Num) and Global_ID, which can be used to form
   Maintenance Entity Point Identifier (MEP_ID).  The MPLS-TP LSP_MEP_ID
   is Node_ID::Tunnel_Num::LSP_Num, and in situations where global
   uniqueness is required, this becomes: Global_ID::Node_ID::
   Tunnel_Num::LSP_Num. In order to realize some Operation,
   Administration and Maintenance (OAM) functions, such as Connectivity
   Verification (CV) [RFC6428], source MEP-ID MUST be inserted in the
   OAM packets, in this way the peer endpoint can compare the received
   and expected MEP-IDs to judge whether there is a mismatch [RFC6371].
   Hence, the two MEP nodes must pre-store each other's MEP-IDs before
   sending the CV packets.

   Obviously, the exchange of MEP_IDs can be accomplished by the Network
   Management System (NMS), but it is complex when the LSPs cross
