IGMP Querier

IGMP Querier Overview

The IGMP Querier feature supports the sending of Internet Group Management Protocol (IGMP) queries
from a router only if the router is a multicast (PIM)-enabled) router. IGMP router functionality will be enabled
only when PIM is enabled on the interface. IGMP router functionality will be disabled when PIM is disabled
on the interface. If IGMP router functionality is enabled and PIM is disabled subsequently, then the router
functionality will be disabled.
