A method is provided for a network including a plurality of nodes where a originating node broadcasts an address request or change PDU. When the PDU is received at a receiving node, the receiving node determines from a look-up routing table whether the broadcast PDU was received on an optimal interface, i.e. an interface which defines the shortest path between the originating and receiving nodes. If the interface was determined to be optimal, the receiving node forwards the request PDU along every interface belonging to the receiving node except the optimal interface, otherwise, the receiving node drops the request PDU. When node address information concerning the originating node cannot be obtained from the routing database of the receiving node, a unique medium node is located to assist in making the optimal interface determination. The method completely avoids the formation of loops thereby improving the performance of a telecommunication management network.
