Multicast Router Port - where to enable

Hi Everyone,

In unifi you can set a port on a switch as a Multicast Router Port. Should this only be enabled on the port where your router is connected?

UniFi supports multicast but what are you trying to do?

Sorry to have waisted your time. Was switching broadcast and multicast. Tought that I had to enable this on the port with a router that was going to be a DHCP-server.
