       Configuration of Dynamic MPLS Transport Profile PseudoWire
                 draft-ietf-pals-mpls-tp-oam-config-02

Abstract

   This document defines extensions to LDP to configure proactive OAM
   functions for both SS-PW and MS-PW when the PW control plane is used.

1.  Introduction

   There are two documents that define MultiProtocol Label Switching
   (MPLS) Pseudowire (PW).  [RFC3985] defines Singel Segment PW (SS-PW)
   and [RFC5659] defines Multi-Segment PW (MS-PW).  The two documents
   expain how to provide emulated services over an MPLS Packet Switched
   Network (PSN).  The MPLS Transport Profile (MPLS-TP) is described in
   [RFC5291], which describes a profile of MPLS that introduces the
   operational models that were typically used in transport networks,
   while providing additional Operations, Administration and Maintenance
   (OAM), survivability and other maintenance functions that were not
