  1. Softwire Mesh Multicast draft-ietf-softwire-mesh-multicast-03 MingweiXu, Yong Cui, JianpingWu Shu Yang, Chris Metz, Greg Shephard IETF 84, Vancouver August 2012

  2. Scenarios of Interest (*,G) or (S,G) (S’,G’) (*,G) or (S,G) To simplify the process, stateless one-to-one source address and group address mapping is applied

  3. History • 2006 - 2010: draft-xu-softwire-4over6multicast-00, 01, 02 Focus on IPv4 over IPv6 multicast • October 2010: draft-xu-softwire-mesh-multicast-00 Support IPv4 over IPv6 and IPv6 over IPv4 multicast • March 2011: draft-xu-softwire-mesh-multicast-01 Improve mechanisms for IPv6 over IPv4 multicast • July 2011: draft-xu-softwire-mesh-multicast-02 Address mapping based on RFC 6052 and draft-boucadair-behave-64-multicast-address-format-02 • September 2011: draft-ietf-softwire-mesh-multicast-00 Adopted by Softwire WG • October 2011: draft-ietf-softwire-mesh-multicast-01 Routing among AFBRs, other considerations • April 2012: draft-ietf-softwire-mesh-multicast-02 Improve ASM part • July 2012: draft-ietf-softwire-mesh-multicast-03

  4. Status Update

  5. Updates in Version 03 • Rewrite “inter-AFBR signaling” part and the “E-IP network supports ASM” part • Improve “other considerations” part • 7.1. Other PIM Message Types • Messages of types other than Join or Prune don’t need to be processed • 7.2. Selecting a Tunneling Technology • all AFBRs deploy the same technology recommended • 7.3. TTL • TTL depends on the tunneling technology

  6. Next step • Welcome comments and feedbacks • Ask for WGLC
