Abstract
A method and system for managing the distribution of multicast content are provided. The method involves creating a list of multicast group addresses to be made available to user units supported by a group of nodes. The list is distributed to all of the nodes in the group of nodes. Filters are created to limit the multicast content that each user unit can receive. The filters are created by referencing the list of multicast addresses previously created. The filters are distributed to the appropriate nodes and applied on customer ports.
