RE: new draft on IPv6 CPE router available for review

["Hemant Singh (shemant)" <shemant@cisco.com>]

Barbara,

I (Hemant) already replied to Mark's email and explained why I sent my
email over the weekend. I have no problem with anyone stepping in and
commenting - I was mistaken in thinking that we'd work with David Miles
as one single contact from DSL folks. We, especially, welcome feedback
from Service Provider (SP) operators since it is their network that gets
affected by such a device.

We published a new version of the draft today. This version caters to
two big requests that came to us since posting of the -00 version. The
requests were (a) to support only a link-local address on the WAN
interface, and (b) to support a LAN up first before WAN behavior of the
CPE Router. Please see Change Log for new version of the draft.

Regards.

Hemant & Wes

I'm sorry -- I just subscribed to this group last week (at the
suggestion of David Miles and Mark Townsley). Can you please explain
what you're saying here? I don't want to misinterpret what you're saying
-- but to me it sounds as if you're asking DSL and FIOS access providers
to not participate in the discussions on this list, or to provide
feedback directly to the list? That we are only "permitted" to provide
input via David or Mark? Since that's a very un-IETF way of doing things
(where generally all individual opinions are welcome, independent of
what company they work for), I want to be sure I didn't misunderstand.

I was about to comment on some of the items discussed in this thread,
but wanted to be sure, first, that I understood this particular email
about who was "welcome" to participate. I thought that Mark and David
were providing an interface for providers and operators not comfortable
with direct participation on IETF lists, and not that we were somehow
"required" to go through them to have our opinions heard.

Thanks,
Barbara

Folks,

Thanks for everyone's proposals and ideas, but we are not seriously
looking at ideas from individual folks - it's not proving to be very
productive. If you are a DSL or FIOS person, please send your proposals
to David Miles who can collate all proposals and he will also work with
Mark Townsley who works on DSL. We are working with David Miles and have
already incorporated his requests from DSL folks in our next version of
the draft. We don't need any proposals or ideas for cable industry since
we have that covered ourselves. 

Any other industry will be dealt by us on a case by case basis.

Thanks.

Hemant

You're right.

I must explain more clearly my proposal.

For the model where WAN interface only acquires a link-local address, I
see two options for the interface which will be assigned a global IPv6
address sub-delegated from IA_PD via DHCPv6 :

- If there is a logical LAN bridge, which is always up even if the LAN
interfaces attached to it are individualy down, CPE will use the bridge
which will be assigned such a global IPv6 address.
These is no need to add a loopback interface.

- Else the CPE router will use a Loopback interface which will be
assigned such a global IPv6 address.
