In one embodiment, a system that employs IGMP (Internet Group Management Protocol) snooping and client tracking to forward an IP multicast flow between a distribution (e.g., wired or backbone) network and a wireless network without the need to configure a VLAN on either infrastructure. A single IP multicast flow is forwarded natively on the distribution network (e.g., from an IP Multicast enabled router) to an AP, and the AP replicates and forwards the multicast flow to a plurality of domains on the wireless network.
