Technical Summary

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.
