Update of the Pseudowire Control-Word Negotiation Mechanism
RFC 6723, “Update of the Pseudowire Control-Word Negotiation Mechanism”, is a Proposed Standard document published in September 2012 by L. Jin, R. Key, S. Delord, T. Nadeau, S. Boutros. It updates RFC 4447, RFC 6073. It has been obsoleted by RFC 8077 — refer to the newer document for the authoritative version. The canonical text is published by the RFC Editor.
Abstract
The control-word negotiation mechanism specified in RFC 4447 has a problem when a PE (Provider Edge) changes the preference for the use of the control word from NOT PREFERRED to PREFERRED. This document updates RFC 4447 and RFC 6073 by adding the Label Request message to resolve this control-word negotiation issue for single-segment and multi-segment pseudowires. [STANDARDS-TRACK]
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
