Usage Guidelines
To configure the dual IPv4 and IPv6 template, enter the sdm prefer dual-ipv4-and-ipv6 global

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.
