Multicast support for dual stack-lite and internet protocol version six rapid deployment on internet protocol version four infrastructures

摘要

A method implemented by a network apparatus comprising receiving a Multicast Listener Discovery (MLD) membership report message from a host, sending an Automatic IP Multicast Tunneling (AMT) Relay discovery message comprising an anycast address for a border relay (BR) via an IPv4 network, receiving an AMT Relay advertisement message comprising a unicast address for the BR via the IPv4 network, sending an AMT request message to the BR via an AMT tunnel, receiving an AMT query message comprising a MLD listener query from the BR via the AMT, sending an AMT membership message comprising the MLD membership report message of the host to the BR via the AMT tunnel, and receiving an AMT multicast data message comprising an encapsulated IPv6 multicast message from the BR via the AMT tunnel.

1. A method implemented by a network apparatus comprising:
receiving an Internet Group Management Protocol (IGMP) membership report message from a host; sending an aggregated IGMP membership report message to an Address Family Transition Router (AFTR) via an Internet Protocol (IP) version four (IPv4) in IP version six (IPv6) tunnel established with the AFTR across an IPv6 network; receiving an IGMP query message from the AFTR via the IPv4 in IPv6 tunnel; and receiving an encapsulated IPv4 multicast message for an IPv4 group from the AFTR via the IPv4 in IPv6 tunnel.
