Abstract

   This document specifies how use of proactive Connectivity
   Verification, Continuity Check, and Remote Defect Indication for the
   MPLS Transport Profile [RFC6428] affects operation and management
   function election for PW VCCV [RFC5085], [RFC5885].

1.  Introduction

   Proactive Connectivity Verification (CV), Continuity Check (CC), and
   Remote Defect Indication (RDI) for the MPLS Transport Profile
   [RFC6428] are applicable to all constructs of the MPLS-TP, including
   pseudowires (PWs).  If control plane is used to operate and manage PW
   s then the procedures defined in [RFC5085] and [RFC5885] should be
   used to select proper type of Control Channel and corresponding type
   of Connectivity Verification.  This document specifies how signaling
   and selection processes are modified to ensure backward compatibility
   and allow use of proactive CV-CC-RDI over MPLS-TP PWs.
