Abstract: A method, apparatus and computer program product for providing IP multicast over split plane wireless LAN. An access tunnel (AT) is defined as an IP multicast interface at a first network device. The AT is capable of communicating with a second network device that is an Internet Protocol (IP) multicast receiver, wherein a local Virtual Local Area Network (VLAN) the first device serves the second network device's mobility VLAN. The first network device sends a query to the second network device over the AT and receiving, in response to the sending the query, a report. A data structure is built defining a multicast group membership from the report, and multicast data is forwarded in accordance with the data structure.
