A method of reconfiguring a data unit communication network that comprises bridge nodes is described. Each bridge node comprises two or more ports for receiving and sending data units, a controller for controlling said bridge node and for handling received data units, and a record for associating data unit address information with port identification information. The controller is capable of querying said record for determining which one or more ports to forward a received data unit to. The method comprises performing a topology reconfiguration procedure for said data unit communication network when detecting an occurrence of any one of one or more topology reconfiguration conditions, and performing a purge procedure of the records of the bridge nodes when detecting an occurrence of an indication of an upcoming topology reconfiguration of the data unit communication network, the indication being different from any of said topology reconfiguration conditions, and continuing to handle data units in the bridge nodes during the purge procedure.
