Gateway-Initiated IPv6 Rapid Deployment on IPv4 Infrastructures (GI 6rd)
Draft of message to be sent after approval:
From: The IESG <firstname.lastname@example.org> To: "Nevil Brownlee" <email@example.com> Cc: The IESG <firstname.lastname@example.org>, <email@example.com>, <firstname.lastname@example.org> Subject: Results of IETF-conflict review for <draft-tsou-softwire-gwinit-6rd-06.txt> The IESG has completed a review of <draft-tsou-softwire-gwinit-6rd> consistent with RFC5742. The IESG has concluded that this work is related to IETF work done in the softwire WG, but this relationship does not prevent publishing.

Technical Summary This document proposes an alternative 6rd deployment model to that of RFC 5969. The basic 6rd model allows IPv6 hosts to gain access to IPv6 networks across an IPv4 access network using 6-in-4 tunnels. 6rd requires support by a device (the 6rd-CE) on the customer site, which must also be assigned an IPv4 address. The alternative model described in this document initiates the 6-in-4 tunnels from an operator-owned gateway collocated with the operator's IPv4 network edge, rather than from customer equipment. The advantages of this approach are that it requires no modification to customer equipment and avoids assignment of IPv4 addresses to customer equipment. The latter point means less pressure on IPv4 addresses in a high-growth environment. Working Group Summary The software WG reviewed this document but there was no consensus to publish it as a WG document due to lack of interest. Document Quality Ralph Droms reviewed the document and concluded that the IESG note included below is appropriate. Personnel Ralph Droms is the responsible AD for the IESG review of this document. IESG Note The IESG has concluded that this work is related to IETF work done in the softwire WG, but this relationship does not prevent publishing.
