Abstract

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 the control plane is used to operate and manage PWs then the procedures defined in [RFC5085] and [RFC5885] should be used to select the proper type of Control Channel and the 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.

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.
