Abstract
A switch receives a first query which requests a response from all hosts in the network, wherein the switch is a next-hop switch of a first set of the hosts in a multicast group, wherein the first query is an Internet Group Management Protocol (IGMP) all-host query message, and wherein the first query is generated by an IGMP querying host and transmitted via one or more intermediate switches. The switch tracks join messages received from the first set of the hosts in response to the first query, wherein a respective join message indicates that a corresponding host is to remain in the multicast group. Responsive to determining that the tracked join messages meet a predetermined threshold, the switch consolidates the tracked join messages by forwarding a reduced number of join messages, thereby reducing a total number of join messages propagated to the IGMP querying host via the intermediate switches.
