Abstract
In one embodiment, an apparatus includes a processing circuit and logic integrated with and/or executable by the processing circuit. The logic is configured to cause the processing circuit to handle Internet Group Membership Protocol (IGMP) messages received from other devices in a network. Also, the logic is configured to cause the processing circuit to create a general query solicit (GQS) message configured to solicit a general query (GQ) from a multicast snooping querier coupled with the apparatus. In another embodiment, a method includes handling, using a switch in a network, IGMP messages received from other devices in the network, and creating, using the switch, a GQS message configured to solicit a GQ from a multicast snooping querier coupled with the switch. Other systems, methods, and computer program products are described in more embodiments.
