Usage Guidelines
IGMP report suppression is supported only when the multicast query has IGMPv1 and IGMPv2 reports. This
feature is not supported when the query includes IGMPv3 reports.
The device uses IGMP report suppression to forward only one IGMP report per multicast router query to
multicast devices. When IGMP report suppression is enabled (the default), the device sends the first IGMP
report from all hosts for a group to all the multicast routers. The device does not send the remaining IGMP
reports for the group to the multicast routers. This feature prevents duplicate reports from being sent to the
multicast devices.
If the multicast router query includes requests only for IGMPv1 and IGMPv2 reports, the device forwards
only the first IGMPv1 or IGMPv2 report from all hosts for a group to all of the multicast routers. If the
multicast router query also includes requests for IGMPv3 reports, the device forwards all IGMPv1, IGMPv2,
and IGMPv3 reports for a group to the multicast devices.
If you disable IGMP report suppression by entering the
no ip igmp snooping report-suppression
command,
all IGMP reports are forwarded to all of the multicast routers.
Examples
This example shows how to disable report suppression:
Device(config)#
no ip igmp snooping report-suppression
You can verify your settings by entering the
show ip igmp snooping
privileged EXEC command.
