In and out. It eliminates transmitting the combined multicast traffic unnecessarily to each port. Decoder Decoder L2 Switch Encoder L2 Switch Encoder L2 Switch Encoder The use of L2 Switch in this topology is very common. Multicast traffic is repeated on all ports of the switch within the segment but traffic from other segments is not seen. Traffic between the segments is controlled by the L3 switch. Economical and practical solution that is very easy to deploy.
