The IGMP filtering feature operates in the same manner when MVR is used to forward multicast traffic.

Example

Console(config)#ip igmp filter

Console(config)#

ip igmp profile

This command creates an IGMP filter profile number and enters IGMP profile configuration mode. Use the no form to delete a

profile number.

Syntax

Default Setting

Disabled

Command Mode

Command Usage

A profile defines the multicast groups that a subscriber is permitted or denied to join. The same profile can be applied to

many interfaces, but only one profile can be assigned to one interface. Each profile has only one access mode; either

permit or deny.

Example

Console(config)#ip igmp profile 19

Console(config-igmp-profile)#

permit, deny

This command sets the access mode for an IGMP filter profile. Use the no form to delete a profile number.

Syntax

{permit | deny}

Default Setting

Deny

Command Mode
