Technical Summary This document defines a mechanism for transporting IPv4 multicast traffic over single-stack IPv6 multicast service provider's networks. This is achieved through the use of the underlying IPv6 multicast distribution tree. The IPv4 traffic is statelessly encapsulated in IPv6. The main benefit of this solution is using an IPv6 multicast network for the efficient distribution of IPv4 based multicast content. Working Group Summary There is consensus in the WG for the publication of this document. A question was raised about scope overlap between this document and RFC8114 (Delivery of IPv4 Multicast Services to IPv4 Clients over an IPv6 Multicast Network). The two differ in the RFC8114 covers multicast for DSLite based networks, whereas this document is for multicast over mesh based provider backbone networks. Text has been added to the Introduction of this document to clarify the difference in scope and the authors of RFC8114 have agreed the text. Document Quality One of the authors (Shu Yang) stated that the Bitway company (a networking device company in China) have implemented a prototype. Personnel Ian Farrer (Softwire co-chair), is the Document Shepherd. Eric Vyncke is the Responsible AD.
