The invention relates to an Ethernet ring node () comprising a plurality of ports including at least two ring ports and at least one non-ring port. The Ethernet ring node comprises a multicast list including information on which port multicast traffic belonging to a multicast group should be sent. A control unit is provided configured to control a traffic distribution of multicast traffic to the different ports of the Ethernet ring node based on the information provided in the multicast list. Furthermore, a detector is provided detecting a topology change of the Ethernet ring in which the Ethernet ring node is provided. When such a topology change is detected, all multicast traffic is transmitted to the at least two ring ports for a predefined period of time, and multicast traffic transmitted to the non-ring ports is transmitted in accordance with the information provided in the multicast list.
