At that point, multicast is handled just like any other udp
packet.  It will go where you have routed the destination
address, or the default route if there is nothing more
specific.  The sending application should also be able to
control it by binding its socket to the interface it
wants to use.  If you want it to go to multiple interfaces
or track listener's IGMP joins you'll need multicast
routing software and I'm not sure about the current state
of that for Linux.  Years ago I used something called smcroute
for some static distribution paths but I never got any of
the PIM based versions to work.
