    Abstract: A method, apparatus and computer program product for providing seamless Internet Protocol multicast connectivity in unified networks is presented. The systems disclosed herein are able to transfer, from a designated (i.e., first) VLAN to a roaming (i.e., second) VLAN, a multicast stream from a multicast server in a mobility VLAN that is not available at the roaming VLAN. In operation, example embodiments of the present invention receive a report identifying a roaming mobile unit as a member of a first VLAN and forward the report to a first mobility switch in the first VLAN. The multicast stream is then received and forwarded toward the roaming mobile unit in the second VLAN so that transfer of the multicast stream from the first VLAN to the second VLAN is seamless.
