I have a Mikrotik router RB2011ViAS-IN that has port 1 setup for the Wan and all of the others as the LAN.
The router is setup to provide DHCP address out the lan ports.
I have a HDMI to IP encoder connected to port 4 setup to provide a 3 Mb Multicast IP video stream.
I have 2 PCs connected to ports 3 and 8.
I login to the router and clicked on the interfaces button and can see the network traffic on each interface.
On ether4 (encoder) it is showing around 3Mb RX
On ether3 & ether8 (PCs) it is showing around 3Mb Tx.
My problem is neither PC is connected to the Multicast stream. So it seems the router is just blasting the data to everyone regardless if they want the stream or not.
Is this expected? Is there some setting in the router so the stream is only sent to PCs that request it?
I ran an app (igmpquery) and it did NOT show any igmp connection between the PCs and the streaming source.
If I started a stream on a PC then igmp did show a connection from the streaming source to the PC.
