Usage Guidelines To configure the dual IPv4 and IPv6 template, enter the sdm prefer dual-ipv4-and-ipv6 global
configuration command and reload the switch.
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.
Examples This example shows how to enable MLD snooping listener-message-suppression:
Switch(config)# ipv6 mld snooping listener-message-suppression
This example shows how to disable MLD snooping listener-message-suppression:
