Abstract
Systems and methods for differentiating between a duplicate MAC address situation and a multiple MAC address movement situation are provided. A node receives a new MAC address determines if it is a known or unknown MAC address by comparing it with a stored MAC address table. If it is a previously known MAC address, the node initiates a duplicate MAC address detection process to determine if at least one of the duplicate MAC addresses is no longer valid or is the result of a MAC mobility event.
