Hi
As shown in the graph attached:
A. I have some UDP Data Generators (DG), which send the data (Soil Moisture, Temperature, ...) on routed paths to the Core Router (CR).
B. Monitoring Agents (MA) will connect to the CR via PPTP.
C. I need to send all the received data (UDP stream) to all MAs simultaneously.

I think I should use a form of Multicast between CR and PPTP Clients;
if I'm right, I am restricted to config multicast between CR and PPTP Clients ONLY, not on other parts of the network.

I don't know How to do this. Can anyone help me please ?
Thanks
