Pseudowire Setup and Maintenance Using the Label Distribution Protocol

Overview

RFC 8077, “Pseudowire Setup and Maintenance Using the Label Distribution Protocol”, is an Internet Standard document published in February 2017 by L. Martini, G. Heron. It obsoletes RFC 4447, RFC 6723. The canonical text is published by the RFC Editor.

Abstract

Layer 2 services (such as Frame Relay, Asynchronous Transfer Mode, and Ethernet) can be emulated over an MPLS backbone by encapsulating the Layer 2 Protocol Data Units (PDUs) and then transmitting them over pseudowires (PWs). It is also possible to use pseudowires to provide low-rate Time-Division Multiplexed and Synchronous Optical NETworking circuit emulation over an MPLS-enabled network. This document specifies a protocol for establishing and maintaining the pseudowires, using extensions to the Label Distribution Protocol (LDP). Procedures for encapsulating Layer 2 PDUs are specified in other documents.

This document is a rewrite of RFC 4447 for publication as an Internet Standard.
