Usage Guidelines
MLD snooping listener message suppression is equivalent to IGMP snooping report suppression. When
it is enabled, received MLDv1 reports to a group are forwarded to IPv6 multicast switchs only once in
every report-forward time. This prevents the forwarding of duplicate reports.
Examples The following example shows how to enable MLD snooping listener message suppression:
Switch# configure terminal
Enter configuration commands, one per line.
Switch(config)# ipv6 mld snooping listener-message-suppression
Switch(config)# end
Switch#
The following example shows how to disable MLD snooping listener message suppression:
Switch# configure terminal
Enter configuration commands, one per line.
Switch(config)# no ipv6 mld snooping listener-message-suppression
Switch(config)# end
Switch#
You can verify your settings by entering the show ipv6 mld snooping [vlan vlan-id] user EXEC
command.
