Be aware, that IGMP snooping breaks some(!) IPv6 multicast (e.g.
DHCPv6). Affects whole EX-series and current plan is to fix it sometime
end of year (Q4 release). If you use IPv4 multicast and need IGMP
snooping to prevent flooding and plan to use e.g. stateful DHCPv6, that
might be a showstopper for now and the VLANs where IGMP snooping is
