RFC 6723: Update of the Pseudowire Control-Word Negotiation Mechanism
This RFC has been replaced. Do not implement against it for new work — it was formally obsoleted by RFC 8077.
Current document in this lineage: RFC 8077 — Pseudowire Setup and Maintenance Using the Label Distribution Protocol (LDP)
In plain English — editorial summary, not part of the RFC
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]
