Luca, and all,
I concur with Andy's opinion that the reference to RFC 4447 must become
Normative (this will not delay the publication is too often the case:-).
As for Informational vs. Historical, I think that Informational is more
appropriate because, AFAIK, the technique defined in draft-kompella is not
just a documenting an existing solution - it describes is THE ONLY deployed
solution for the problem. (If this statement happens to be factually
incorrect, I would be happy to learn about the deployed alternatives.)
no, there are several ( I think 3 ) implementations of the
l2vpn-singalling standards track document also known as rfc6074.
There are several deployments of rfc6074.
As 10 years ago we had several deployments of "draft-martini" which over
time are being updated to rfc4447 , there are some deployments of the
solution described in the draft-kompella-l2vpn-l2vpn-07.txt. I still
think that an historical RFC would fit this solution , unless we plan on
expanding it , and pursuing new enhancements to it.

I concurr with Andy.
Given that the WG has made a decision on which control plane technology
is the standard track technology we should have a statement in this
document pointing to the standard track rfc4447 so it is clear to anyone
reading the document.
In the same way we published the draft-martini documents as historical
ee should publish this document as historical rfc, to document existing

Speaking as PWE3 co-chair, I would be happier if this draft required
that routers that implement this solution also implement RFC 4447,
that RFC 4447 be configured as the default mechanism for pseudowire
signaling, and that RFC 4447 was moved from an informational to a
normative reference. In practice, I know that routers that implement
this also do implement RFC 4447, but I would like to see it in the RFC

The IESG plans to make a decision in the next few weeks, and solicits
final comments on this action. Please send substantive comments to the

Layer 2 Virtual Private Networks (L2VPNs) based on Frame Relay or ATM
circuits have been around a long time; more recently, Ethernet VPNs,
including Virtual Private LAN Service, have become popular.
Traditional L2VPNs often required a separate Service Provider
infrastructure for each type, and yet another for the Internet and IP
VPNs. In addition, L2VPN provisioning was cumbersome. This document
presents a new approach to the problem of offering L2VPN services
where the L2VPN customer's experience is virtually identical to that
offered by traditional Layer 2 VPNs, but such that a Service Provider
can maintain a single network for L2VPNs, IP VPNs and the Internet,
as well as a common provisioning methodology for all services.
