Multicast on all ports - IPTV

EDIT: SORRY ABOUT WRONG FORUM SECTION

Hi,

In scenario from picture, is it possible to resolve issue where multicast is spread to all ports?

Technical info:

Multicast servers based on Ubuntu and dvblast (udp multicast)
Set top boxes are from Amino, Aminet110.
Streams are 232.232.1.1 - 232.232.1.100


The system is running perfectly now on Allied Telesis switch, but I need more ports so I would like to switch to 2x Mikrotik

What I have tried is playing with igmp proxy and multicast packet and PIM but with no success.
Also, can I use ‘switch’ feature or ports need to be in bridge for this scenario ?

IGMP snooping is not currently supported by these switches.

Neither. For IGMP proxy to work as you possibly expect all your client ports should be routed.
