Configuring IGMP Snooping and MVR
TCN flood query count
Vlan 1:
--------
IGMP snooping
Immediate leave
Multicast router learning mode
Source only learning age timer
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.
Static connections to multicast routers are supported only on switch ports.
Note
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 gigabitethernet0/2
Switch(config)# end
Switch# show ip igmp snooping mrouter vlan 200

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.
