The first example consists only of a single bridge, a single multicast source device, and a couple of multicast client devices. See a network scheme below.
First, create a bridge interface with enabled IGMP snooping. In this example, there is no active IGMP querier (no multicast router or proxy), so a local IGMP querier must be enabled on the same bridge. This can be done with a multicast-querier setting. If the LAN does not have an active IGMP querier, the unregistered IP multicast will be flooded and multicast entries will always timeout from the multicast database.

/interface bridge
add igmp-snooping=yes multicast-querier=yes name=bridge1 |
Then add necessary interfaces as bridge ports.

/interface bridge port
add bridge=bridge1 interface=ether2
add bridge=bridge1 interface=ether3
add bridge=bridge1 interface=ether4
add bridge=bridge1 interface=ether5 |
The basic IGMP snooping configuration is finished. Use "/interface bridge mdb print" command to monitor the active multicast groups. If necessary, you can configure an IP address and DHCP server on the same bridge interface.
