I think it is a solution draft for draft-ietf-mboned-v4v6-mcast-ps, i.e. for mboned. I see it as a solution for how to do multicast in DS-Lite. That it is a more generic solution that has wider applicability is just a bonus. I feel that mboned would have been a good place to do this work, but it was in softwires charter to find a solution, and this is one. I think mboned should review it to check if there are any issues with the solution though. That is happening right now.

Hi Behcet, I'm ready to record in the document whatever the WG agrees to do. But as far as I know the solution which consists in encapsulating all multicast flows to the unicast AFTR has not been accepted by the working group. The drawbacks are even been documented in this draft. I'm aware of the tickets you opened. I already answered several times to those issues by e-mail. I sincerely don't see what I can do more.

The main changes are: * change the title * clarify the solution is generic for any 4-6-4 use case and the solution has been designed with DS-Lite in mind * add a discussion about scoping: preserve the scope when translation multicast addresses * add a note only IPv4-in-IPv6 encap is detailed in the document but other tunnelling techniques may be defined in the future * update the security section with some discussions related to scoping. * + other editorial changes.

Title : Delivery of IPv4 Multicast Services to IPv4 Clients over an IPv6 Multicast Network Author(s) : Jacni Qin Mohamed Boucadair Christian Jacquenet Yiu L. Lee Qian Wang Filename: draft-ietf-softwire-dslite-multicast-03.txt Pages : 20 Date: 2012-08-23 Abstract: This document specifies a solution for the delivery of IPv4 multicast services to IPv4 clients over an IPv6 multicast network. The solution relies upon a stateless IPv4-in-IPv6 encapsulation scheme and uses the IPv6 multicast distribution tree to deliver IPv4 multicast traffic. The solution is particularly useful for the delivery of multicast service offerings to DS-Lite serviced customers.
