Usage
Enabling IGMP on a routing interface requires both the ip igmp command (page 13‐10), which
enables it on the router, and the ip igmp enable command (page 13‐11), which enables it on an
interface. Once these commands are executed, the device will start sending and processing IGMP
multicast traffic. IGMP is disabled by default, both globally and on a per interface basis.
Example
This example shows how to enable IGMP on the router:
B5(su)->router(Config)#ip igmp
ip igmp enable
Use this command to enable IGMP on an interface. The no form of this command disables IGMP
on an interface.
Syntax
ip igmp enable
no ip igmp enable
Parameters
None.
Defaults
None.

This example shows how to enable IGMP on the VLAN 1 interface:
B5(su)->router(Config)#interface vlan 1
B5(su)->router(Config-if(Vlan 1))#ip igmp enable
ip igmp version
Use this command to set the version of IGMP running on the router. The no form of this command
