IGMP snooping

CGMP interoperability mode
To return to the default learning method, use the no ip igmp snooping vlan vlan-id mrouter learn cgmp
global configuration command.

Configuring a Multicast Router Port

To add a multicast router port (add a static connection to a multicast router), use the ip igmp snooping
vlan mrouter global configuration command on the switch.
Beginning in privileged EXEC mode, follow these steps to enable a static connection to a multicast
router:
Command
Step 1
configure terminal
Step 2
ip igmp snooping vlan vlan-id mrouter
interface interface-id
Step 3
end
Step 4 show ip igmp snooping mrouter [vlan vlan-id] Verify that IGMP snooping is enabled on the VLAN interface.
Step 5
copy running-config startup-config
To remove a multicast router port from the VLAN, use the no ip igmp snooping vlan vlan-id mrouter
interface interface-id global configuration command.
This example shows how to enable a static connection to a multicast router and verify the configuration:
Switch# configure terminal
Switch(config)# ip igmp snooping vlan 200 mrouter interface gigabitethernet0/1
Switch(config)# end
Switch# show ip igmp snooping mrouter vlan 200
vlan

:IGMP_ONLY
Purpose
Enter global configuration mode.
Specify the multicast router VLAN ID and specify the interface
to the multicast router. For the VLAN ID, the range is 1 to 1005
when the SI is installed and 1 to 4094 when the EI is installed.
Return to privileged EXEC mode.
(Optional) Save your entries in the configuration file.
