Zusammenfassung:	One embodiment of the present invention provides a virtual routing bridge (271) and a virtual switch (261). These modules include a tunnel management module, a packet processor, and a forwarding module. The tunnel management module operates the software as a tunnel gateway capable of terminating an overlay tunnel. During operation, the packet processor, which is coupled to the tunnel management module, identifies in a data packet a virtual Internet Protocol (IP) address associated with a virtual tunnel gateway. The data packet is associated with the overlay tunnel. The forwarding module determines an output port for an inner packet in the data packet based on a destination address of the inner packet.
