Enabling IGMP report suppression

About IGMP report suppression

This feature enables the Layer 2 device to forward only the first IGMP report for a multicast group to its directly connected Layer 3 device. Other reports for the same group in the same query interval are discarded. Use this feature to reduce multicast traffic.
