[Softwires] Fw: I-D Action: draft-ietf-softwire-mesh-multicast-19.txt

Dear Med,

Thank you for the great advices, and we revised and updated the document according to them.  

RFC 8114 is an important reference for our document, and we list it where needed. 

According to RFC4925, supporting multicast is important for both hub-and-spoke and mesh scenario. While RFC 8114 focuses on supporting hub-and-spoke, ours focuses on supporting mesh. Thus we maintain this draft since Oct,2010 (actually Sep,2006 considering draft-xu-softwire-4over6multicast-00).   Although there are some parts in common, softwire mesh is quite different. For example, the basic routing mechanism in control plane between AFBR is different from AFTR.  Thus, we found a new standard is needed when implementing multicast in the mesh scenario, e.g.,CERNET2.

Abstract:
   During IPv6 transition, there will be scenarios where a backbone
   network running one IP address family internally (referred to as
   internal IP or I-IP), while the attached client networks running
   another IP address family (referred to as external IP or E-IP).  The
   I-IP backbone should offer both unicast and multicast transit
   services to the client E-IP networks.

   This document describes the mechanism for supporting multicast across
   a set of E-IP and I-IP networks supporting softwire mesh.  The
   document focuses on IPv4-over-IPv6 scenario, due to lack of real-
   world use cases for IPv6-over-IPv4 scenario.
