  VCCV MPLS-TP Connectivity Verification (CV) Capability Advertisement
                   draft-ietf-pwe3-mpls-tp-cv-adv-05

Abstract

   This document specifies how signaling and selection processes for
   Pseudowire (PW) Virtual Circuit Connectivity Verification (VCCV) are
   modified to ensure backward compatibility and allow use of proactive
   Connectivity Verification (CV), Continuity Check (CC), and Remote
   Defect Indication (RDI) over MPLS Transport Profile (MPLS-TP) PWs.
   This document introduces four new CV types and, to accommodate them,
   a new VCCV Extended CV parameter for PW Interface Parameters Sub-TLV
   is defined.

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
   PWs 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.
