Technical Summary

This document specifies a mechanism to signal Point-to-Multipoint (P2MP)
Pseudowires (PW) tree using LDP. Such a mechanism is suitable for any Layer 2
VPN service requiring P2MP connectivity over an IP or MPLS enabled PSN.
A P2MP PW established via the proposed mechanism is root initiated. This
document updates RFC7385 by re-assigning reserved value 0xFF to be the
wildcard transport tunnel type.

Working Group Summary

 The Working Group and its predecessor (PWE3) took a long time
to finish the document. There was not much comment on it in
WGLC. It is none-the-less a useful document which should be
published as part of completing the IETF work on "classical"
Document Quality

This is a well written document that clearly explains how to
signal Root-Initiated Point-to-Multipoint Pseudowire using LDP.
