Command
History
Usage
Information
This command enables the IGMP switch to send General Queries periodically. This is 
useful when there is no multicast router present in the VLAN because the multicast 
traffic does not need to be routed. An IP address must be assigned to the VLAN 
interface for the switch to act as a querier for this VLAN.
show ip igmp snooping mrouter
c e s
Display multicast router interfaces.
Syntax
show ip igmp snooping mrouter
