   MLD snooping allows the switch to examine MLD packets and make forwarding decisions based
   on their content.
   You can configure the switch to use MLD snooping in subnets that receive MLD queries from
   either MLD or the MLD snooping querier. MLD snooping constrains IPv6 multicast traffic at Layer
   2 by configuring Layer 2 LAN ports dynamically to forward IPv6 multicast traffic only to those ports
   that want to receive it.

   in real deployment I rather leave the ipv6 flooding rather to do the content look up by the switch.

   However, the MLD(multicast listener Discovery) snooping is an awesome feature
