A leaf initiated point-to-multi-point connection, particularly within an ATM network via ATM signaling, is established. An IGMP to UNI translation and a UNI call sequence to indicate when and where a point-to-multi-point connection should be provided. Per IGMP join stimulus, a Setup message is sent from the leaf to an end point, or Root, to request to join a known multi-point connection. Routing information is inserted into the Setup message for routing to the leaf. The Root end point originates a point to multi-point call to the leaf using the routing information inserted into the Setup message. The Setup message is rejected by the endpoint. |
