IGMP V3 Source Filter
Note: Any emitter can send IP packets to a multicast address, so it could happen that by mistake
two emitters send to the same multicast address. The resultant multicast stream would be
completely garbled. IGMP V3 gives the user the possibility to indicate a source address, so
that by indicating "IGMP V3 include <IP multicast source address> the unit will take only the
IP packets coming from the indicated source address, thus eliminating the garbling problem.
