Abstract
A method may include receiving, at a network interface of a first network element, an Internet Group Management Protocol (IGMP) message from a second network element. The method may also include updating first multicast group data associated with the network interface based on the received IGMP message, the first multicast group data including one or more entries setting forth a multicast group and one or more other network elements which are members of the multicast group. The method may additionally include determining whether the second network element is the sole member of its multicast group based on the IGMP message and the first multicast group data. The method may further include forwarding the IGMP message to a switching element of the first network element in response to determining that the second network element is the sole member of its multicast group, the switching element communicatively coupled to the network interface.
