MLD snooping listener message suppression is equivalent to IGMP snooping report suppression. When
enabled, received MLDv1 reports to a group are forwarded to IPv6 multicast routers only once in every
report-forward time. This prevents the forwarding of duplicate reports.

Switch(config)# ipv6 mld snooping listener-message-suppression
This example shows how to disable MLD snooping listener-message-suppression:
