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]

Abstract as published in the RFC, via rfc-editor.org.

What “Proposed Standard” means
