ip igmp proxy

Configures IGMP proxy on an interface
Syntax
ip igmp proxy [ group-filter access-list ]
no ip igmp proxy [ group-filter access-list ]
Command Default

IGMP proxy is not enabled.

Parameters
group-filter
Specifies filtering out groups in proxy report messages.
access-list
Specifies the access list name or number you want filtered out.
Modes

Interface configuration mode

Usage Guidelines

The no form of this command disables IGMP proxy on an interface.

IGMP proxy is supported only in PIM dense environments where there are IGMP clients connected to the device. PIM DM must be enabled in passive mode.

IGMP proxy is not supported on interfaces on which PIM sparse mode (SM) or Source Specific Multicast (SSM) is enabled.

Enter the ip igmp proxy command without the group-filter keyword to remove the group-filter association without disabling the proxy.

Examples

This example enables IGMP proxy on an interface. It first shows how to configure PIM globally, configure an IP address that will serve as the IGMP proxy for an upstream device on interface 1/3/3, enable PIM passive on the interface, and then enable IGMP proxy. 

device(config)# router pim
device(config)# interface ethernet 1/3/3
device(config-if-e1000-1/3/3)# ip address 10.95.5.1/24
device(config-if-e1000-1/3/3)# ip pim passive
device(config-if-e1000-1/3/3)# ip igmp proxy

The following example filters out the ACL1 group in proxy report messages. 

device(config)# router pim
device(config)# interface ethernet 1/3/3
device(config-if-e1000-1/3/3)# ip address 10.95.5.1/24
device(config-if-e1000-1/3/3)# ip pim passive
device(config-if-e1000-1/3/3)# ip igmp proxy group-filter ACL1
