    Label Distribution Protocol Extensions for Proactive Operations,
 Administration and Maintenance Configuration of Dynamic MPLS Transport
                           Profile PseudoWire
                 draft-ietf-pwe3-mpls-tp-oam-config-01

Abstract

   This document specifies extensions to the Label Distribution Protocol
   (LDP) to configure and control proactive Operations, Administration
   and Maintenance (OAM) functions, which are suitable for dynamic
   Single-Segment PseudoWire (SS-PW) and Multi-Segment PseudoWire (MS-
   PW).
