Is IPv6 MLD snooping supported in RouterOS yet? I searched here and found the same question dated June 2012, but no answer.
If it is not yet supported, then when?
MLD snooping is needed in IPv6 for the same reason IGMP snooping is needed in IPv4 - to make sure that multicast traffic goes only to listeners. Without MLD snooping, multicast IPv6 traffic is flooded out all connected switch ports.
