Abstract
When multi-destination traffic is distributed through a host or switch, the decision to distribute each frame is performed by each egress port and not the ingress port. Within a link aggregation group, the multi-destination frame is sent to each of the egress ports within the link aggregation group. Each of such ports will then determine whether it should re-transmit the frame. If not, the frame is discarded.
