Command Usage
Depending on your network connections, IGMP snooping may not always be
able to locate the IGMP querier. Therefore, if the IGMP querier is a known
multicast router/switch connected over the network to an interface (port or
trunk) on your switch, you can manually configure that interface to join all the
current multicast groups.
Example
The following shows how to configure port 11 as a multicast router port within
VLAN 1:
show ip igmp snooping mrouter
Use this command to display information on statically configured and dynamically
learned multicast router ports.
Syntax
show ip igmp snooping mrouter [vlan vlan-id]
vlan-id - VLAN ID (Range: 1-4094)
Default Setting
Displays multicast router ports for all configured VLANs.
Command Mode
Privileged Exec
Command Usage

The following shows the ports in VLAN 1 which are attached to multicast routers:
Console(config)#ip igmp snooping vlan 1 mrouter ethernet 1/11
