Defaults
None.
Usage
Enabling IGMP on a routing interface requires both the ip igmp command (page 10‐10), which
enables it on the router, and the ip igmp enable command (page 10‐10), 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.
Mode
Interface configuration: G3(su)‐>router(Config‐if(Vlan 1))#
Example
This example shows how to enable IGMP on the VLAN 1 interface:
G3(su)->router(Config)#interface vlan 1
G3(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
resets IGMP to the default version of 2 (IGMPv2).
Syntax
ip igmp version version
no ip igmp
Parameters
version
Defaults
None.
Mode
Interface configuration: G3(su)‐>router(Config‐if(Vlan 1))#
Example
This example shows how to set the IGMP version to version 1 on VLAN 1:
G3(su)->router(Config)#interface vlan 1
G3(su)->router(Config-if(Vlan 1))#ip igmp version 1
show ip igmp interface
Use this command to display information about one or more IGMP routing interfaces.
Syntax

Specifies the IGMP version number to run on the router. Valid values are
1, 2, or 3.
