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 enabled.
