ip multicast report-control

Limits report forwarding within the same multicast group to no more than once every 10 seconds.
Syntax
ip multicast report-control
no ip multicast report-control
Command Default

A device in passive mode forwards reports and leave messages from clients to the upstream router ports that are receiving queries.

Modes

Global configuration mode

Usage Guidelines

The no form of this command restores the default.

Note: This feature applies to IGMP V2 only. The leave messages are not rate limited.

This rate-limiting does not apply to the first report answering a group-specific query.

Configure this command to alleviate report storms from many clients answering the upstream router query.

The ip multicast report-control command was formerly named ip igmp-report-control . You can still configure the command as ip igmp-report-control ; however, it is renamed when you configure the show configuration command.

Examples

This example limits the rate of report forwarding within the same multicast group.

Device(config)#ip multicast report-control
