IP Multicast Stub Routing in AOS
PCs 1, 2, 4, and 6 have subscribed to a specific media server content which is delivered on a single multicast stream
and copied once to each segment containing subscribing client PCs.
When using subinterfaces (frame relay PVCs, VLAN subinterfaces, etc.), each subinterface
is a separate logical IP interface. It is possible that a multicast stream may be forwarded
to each subinterface, resulting in the stream being sent multiple times over the same
physical interface.
