In one example embodiment a technique for routing a data packet destined for at least a recipient coupled to the first port is provided. The technique includes receiving a data packet at the second port and transmitting the data packet to the switch fabric. Next, the technique includes routing the data packet from the switch fabric to the third port. Then, the technique includes transmitting the data packet from the third port back to the switch fabric with an indication to route the data packet to the first port. Finally, the technique includes routing the data packet from the switch fabric directly to the first port and transmitting the data packet from the first port to the recipient. ## Claims ### Claim 1 A packet switch device comprising: a first port;
