Abstract:
This memo specifies 4rd technology's multicast component so that IPv4
hosts can receive multicast data from IPv4 servers over an IPv6
network. In 4rd Translation Multicast solution for 4rd and
translation variant of MAP, MAP-T, IGMP messages are translated into
MLD messages at the CE router which is IGMP/MLD Proxy and sent to the
network in IPv6. 4rd Border Relay does the reverse translation and
joins IPv4 multicast group for 4rd hosts. Border Relay as multicast
router receives IPv4 multicast data and translates the packet into
IPv6 multicast data and sends downstream on the multicast tree.
Member CEs receive multicast data, translate it back to IPv4 and
transmit to the hosts. In 4rd encapsulation solution for
encapsulation variant of MAP, MAP-E, IGMP Proxy at the 4rd Customer
Edge router uses IPv4-in-IPv6 tunnel established by MAP-E to exchange
IGMP messages to establish multicast state at MAP Border Relay so
that MAP Border Relay can tunnel IPv4 multicast data to IPv4 hosts
connected to MAP Customer Edge device.
