Abstract:
This memo specifies MAP-E's multicast component so that IPv4 hosts
can receive multicast data from IPv4 servers over an IPv6 network.
In the encapsulation solution for encapsulation variant of Mapping of
Address and Port (MAP), MAP-E, IGMP Proxy at the MAP-E Customer Edge
router uses IPv4-in-IPv6 tunnel established by MAP-E to exchange IGMP
messages to establish multicast state at MAP-E Border Relay so that
MAP-E Border Relay can tunnel IPv4 multicast data to IPv4 hosts
connected to MAP-E Customer Edge device. In the Translation
Multicast solution for the translation variant of MAP, MAP-T and 4rd,
IGMP messages are translated into MLD messages at the CE router which
is IGMP/MLD Proxy and sent to the network in IPv6. MAP-T/4rd Border
Relay does the reverse translation and joins IPv4 multicast group for
MAP-T/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.
