Hi James

I think we are agreeing on lots points except one important point i.e.
SHOULD or SHOULD NOT make individual submissions WG docs without a

My main objection of making individual submissions WG docs without well
thought through strategy is it takes away the focus and confuse WG,
customers and burden vendors. Additionally, TRILL WG should focus on the
priority items that was agreed in Taipei. Adding additional WG docs is
not helping anyways. I am in the opinion that WG should identify
priority Work areas, then form strategy around it, bring together
different ideas to form well thought through solutions. 

Secondly, it seems you are in the opinion that to get WG input the draft
need to be WG document. I disagree with that. A draft does not need to
be in WG status to get WG feedback. Authors should solicit feedback
through the mailing list. Making a WG status is not going to change

We might agree on that point, but it's not the question at hand.  The
question at hand is whether to adopt a draft.

	"This includes a MIB module and
other pieces needed for operations, but also additional ways to extend
and optimize TRILL for the properties of the networks on which it is

This seems to me to be an additional way to extend TRILL for the
property of a network -- specifically, an IP network.

Granted, I'm not thrilled about the idea of adding a new means to reach
mutual encapsulation.  I assume the authors have a good reason to do
this, and have interesting ideas on how and why it should be done.  The
important point is that I think this working group is the best possible
forum to air those ideas.

Some efforts do indeed follow that simple linear path -- idea, BOF,
charter, WG, publication.  But that's certainly not the only path, nor
perhaps even the most common.  Adoption by an existing WG of new
in-scope documents is something that I view as crucially important to
continued WG viability.  Without it, protocols just grow like weeds as
new extensions are otherwise developed, deployed, and documented without
the help of WG consensus using the individual-submission RFC publication

Failing to adopt does not foreclose publication of an RFC describing
this extension, nor any other work by the authors.  It simply
disconnects the WG from the process.

Sending TRILL over IP off to the individual-submission world without WG
input would, I think, be a poor result of this exercise.  I've been
through that problem as PPPEXT chair, and it's no fun.
