Re: more than single stream comming on multicast

In Any Source Multicast (ASM) mode, a receiver for a given multicast group will receive all streams from any source sending to that multicast group.

If this is not the behavior you want, you need to look at Source Specific Multicast (SSM), where the receiver not only the multicast group that it wants to join but also the specific source. This requires the receiver to support IGMPv3.

You certainly can if the receiver doesn't support IGMPv3.
