Configuring IGMP Snooping
TCN flood query count :2
Vlan 1:
--------
IGMP snooping :Enabled
Immediate leave :Disabled
Multicast router learning mode :pim-dvmrp
Source only learning age timer :10
CGMP interoperability mode :IGMP_ONLY
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.
Note Static connections to multicast routers are supported only on switch ports.
Beginning in privileged EXEC mode, follow these steps to enable a static connection to a multicast
router:
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 gigabitethernet0/2
Switch(config)# end
Switch# show ip igmp snooping mrouter vlan 200
vlan ports

Configuring a Host Statically to Join a Group
Hosts or Layer 2 ports normally join multicast groups dynamically, but you can also statically configure
a host on an interface.
Command Purpose
Step 1
configure terminal Enter global configuration mode.
Step 2
ip igmp snooping vlan vlan-id mrouter
interface interface-id
Specify the multicast router VLAN ID and specify the interface
to the multicast router.The VLAN ID range is 1 to 4094.
Step 3
end Return to privileged EXEC mode.
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 (Optional) Save your entries in the configuration file.
