Abstract:
This memo specifies multicast component for MAP-E and Light Weight
4over6 so that IPv4 hosts can receive multicast data from IPv4
servers over an IPv6 network. Two types of solutions are developed,
encapsulation and translation. In the encapsulation solution for
MAP-E and lw4o6, IGMP Proxy at the MAP-E Customer Edge router/lwB4
uses IPv4-in-IPv6 tunnel to exchange IGMP messages to establish
multicast state at MAP-E Border Relay/lwAFTR so that MAP-E Border
Relay/lwAFTR can tunnel IPv4 multicast data to IPv4 hosts. In the
Translation Multicast solution for MAP-T, 4rd and lw4o6, IGMP
messages are translated into MLD messages and sent to the network in
IPv6. MAP-T/4rd Border Relay/lwAFTR does the reverse translation and
joins IPv4 multicast group for the hosts. Border Relay/lwAFTR as
multicast router receives IPv4 multicast data and translates the
packet into IPv6 multicast data and sends downstream on the multicast
tree. Member CEs/lwB4s receive multicast data, translate it back to
IPv4 and transmit to the hosts.
