Multicast support for internet protocol version four residual deployment via encapsulation or translation

摘要

Included is an Internet Protocol (IP) version four (IPv4) Residual Deployment via IP version six (IPv6) (4rd) customer edge (CE) comprising a transceiver configured to communicate with an IPv6 network, and a processor coupled to the transceiver and configured to receive multicast packets from a multicast source via the IPv6 network, and transmit the multicast packets to a host. The disclosure also includes a 4rd border relay (BR) comprising a transceiver configured to communicate with an IPv6 network, and a processor coupled to the transceiver and configured to receive multicast packets from a multicast source, and transmit the multicast packets to a host via the IPv6 network and a 4rd customer edge (CE).

1. An Internet Protocol (IP) version four (IPv4) Residual Deployment via IP version six (IPv6) (4rd) customer edge (CE) router comprising:
a transceiver configured to communicate with an IPv6 network; and a processor coupled to the transceiver and configured to:
receive multicast packets from a multicast source via the IPv6 network;transmit the multicast packets to a host;transmit a multicast membership report message to a 4rd border relay (BR) via the IPv6 network, wherein the multicast membership report message is transmitted to the BR on behalf of the host, and wherein the multicast membership report message is transmitted via anycast;receive a unicast address of the BR in response to the multicast membership report message, wherein the multicast membership report message is associated with a multicast group; andtransmit a plurality of subsequent multicast membership report messages associated with the multicast group on behalf of the host,wherein all the subsequent multicast membership report messages are transmitted to the BR using the BR's unicast address.
