Method and apparatus for layer 2 multicast traffic management

摘要

One embodiment pertains to a switching device which is configured to provide multicast traffic management in a layer 2 network without layer 3 devices A specific embodiment relates to a method of implementing IGMP multicasting in a layer 2 network. IGMP packets are snooped by multiple switches in the layer 2 network. IGMP query messages are generated by each of the multiple switches. IGMP join report messages are forwarded by each of the multiple switches to all ports on which a querier is present. Other embodiments are also disclosed.
