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] is applicable to all constructs of the MPLS-TP, including
   pseudowires (PWs).  If Control Plane is used to operate and manage PW
   then procedure 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 process modified to ensure backward compatibility and allow
   use of proactive CV-CC-RDI over MPLS-TP PWs.
