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.

Bidirectional Forwarding Detection (BFD) for the Pseudowire Virtual Circuit Connectivity Verification (VCCV)

VCCV provides a control channel that is associated with a pseudowire, as well as the corresponding operations and management functions such as connectivity verification to be used over that control channel.

Proactive Connectivity Verification, Continuity Check, and Remote Defect Indication for the MPLS Transport Profile

This document specifies specific extensions to Bidirectional Forwarding Detection (BFD) and methods for proactive Continuity Check, Continuity Verification, and Remote Defect Indication for MPLS-TP pseudowires, Label Switched Paths, and Sections using BFD as extended by this memo.

Pseudowire Virtual Circuit Connectivity Verification (VCCV): A Control Channel for Pseudowires

This document describes Virtual Circuit Connection Verification procedures for use with pseudo wire connections so that a network operator may use the VCCV procedures to test the network's forwarding plane liveliness.

Pseudowire Setup and Maintenance Using the Label Distribution Protocol (LDP)

This document specifies a protocol for establishing and maintaining the pseudowires, using extensions to the Label Distribution Protocol (LDP).

Pseudowire (PW) Operations, Administration, and Maintenance (OAM) Message Mapping

This document covers the case whereby the ACs and the PWs are of the same type in accordance to the PWE3 architecture such that a homogenous PW service can be constructed.

IANA Allocations for Pseudowire Edge to Edge Emulation (PWE3)

This document allocates the fixed pseudowire identifier and other fixed protocol values for protocols that have been defined in the Pseudo Wire Edge to Edge (PWE3) working group. Detailed IANA

Guidelines for Writing an IANA Considerations Section in RFCs

Many protocols make use of identifiers consisting of constants and other well-known values that must be administered by a central authority to insure that such quantities have consistent values and interpretations in different implementations.

Bidirectional Forwarding Detection (BFD) for IPv4 and IPv6 (Single Hop)

This document describes the use of the Bidirectional Forwarding Detection protocol over IPv4 and IPv6 for single IP hops. Comments on this draft should be directed to

Bidirectional Forwarding Detection (BFD)

This document describes a protocol intended to detect faults in the bidirectional path between two forwarding engines, including interfaces, data link(s), and to the extent possible the forwarding

Key words for use in RFCs to Indicate Requirement Levels

This document defines these words as they should be interpreted in IETF documents as well as providing guidelines for authors to incorporate this phrase near the beginning of their document.
