block multicast traffic

Sun Aug 05, 2018 2:10 am

Hello Sirs,
i have a Mikrotik router connected to a switch that have multicast channels traffic on it, as per image attached.
Exactly 128 Mb of traffic, source destination various addresses in space.
How i can avoid to have this traffic fixed on my ethernet ? I can't drop it because is only "border traffic", neither input or forwarded.
Is there a way to ignore multicast traffic on a ethernet ?
I try to setup an IGMP proxy to filter it, but no idea on how do filtering :)

Thank you in advance.
