Technical Summary
This document specifies a new Virtual Circuit Connectivity
Verification (VCCV) (RFC5085) control channel type for use with
pseudowires (PW) carried over an MPLS network. This new channel type
uses the Generic Associated Channel Label (GAL) (RFC5586) to
distinguish VCCV packets from packets carrying user data. Although the use
of the GAL on PWs in MPLS-TP is defined in RFC6423, this draft specifies
the necessary extensions to VCCV to support the GAL on PWs setup and
maintained using targeted LDP (tLDP).
Working Group Summary
Nothing unusual in the progress of the document.
Document Quality
There are multiple implementations of the GAL for MPLS-TP LSPs and PWs. Many
implementations of the LDP extensions for negotiating the use of the existing
VCCV control channel on a targeted LDP signalled PW are also known to exist.
The document has also been widely reviewed by the original authors of and
contributors to VCCV (RFC5085).
