"just passing through multicast" (as in "same VLAN") should not need
any special configuration.

OTOH, at least EX3300 like to eat multicast unless you turn off 
IGMP snooping ("delete protocols igmp-snooping") - which, annoyingly,
is on-by-default.

Without any "smarts" in the switch, multicast is just like broadcast.
