摘要：
An apparatus comprising a plurality of district boundary bridges (DBBs) in a plurality of second network districts configured to couple to a plurality of core bridges in a core network district and to a plurality of end-stations in the second network districts via a plurality of intermediate switches in the second network districts; wherein the core bridges and the DBBs are aware of a plurality of Media Access Control (MAC) addresses of the DBBs but are not aware of Internet Protocol (IP) addresses and MAC addresses of the end-stations, and wherein the IP addresses of the end-stations are mapped in a directory service (DS) in the core network district to the MAC addresses of the corresponding DBBs in the corresponding second network districts of the end-stations.
