Abstract: It is disclosed a method and a detector capable of resolving unicast flooding in a layer 2 broadcast domain. The method is performed in a detector having a medium access control (MAC) address. The detector receives a first flooded packet having a destination MAC address differing from the detector's MAC address. The detector sends a message to a node in the layer 2 broadcast domain, wherein the type of the node is determined based on the destination MAC address of the first flooded packet and/or based on whether a destination Internet protocol (IP) address of the first flooded packet is an address within the layer 2 broadcast domain. It is advantageous that the message is adapted to trigger the node to announce its MAC address within the layer 2 broadcast domain, causing the unicast flooding to be resolved, by which consumption of available bandwidth is reduced.
