The following limitations apply to IGMP Layer 2 Querier.
IGMP Layer 2 Querier is based on IGMP Snoop. If you disable IGMP Snoop, IGMP Layer 2 Querier does not work until you enable IGMP Snoop and IGMP Layer 2 Querier.
After you enable IGMP Snoop and IGMP Layer 2 Querier on an interface, if the system receives no IGMP query messages, it becomes the querier.
