block multicast traffic

RouterOS General
1

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 192.168.1.1 destination various addresses in 226.0.0.0/8 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 :slight_smile:

Thank you in advance.

Hi. Did you manage to do it after all? Have similar issue.

/ip firewall filter
  add action=drop chain=input dst-address-type=multicast

I just found this thread… but I did it this way…

/interface bridge filter
add action=drop chain=forward in-interface=ether13-Physical-Matrix packet-type=\
    multicast

I needed this for a strange traffic on bridge.
Thank you gotsprings :slight_smile:
