摘要： In one embodiment, a method includes receiving a packet from a source wireless device at a second switch, the source wireless device previously associated with a first switch and roamed to and associated with the second switch, wherein a point of presence for the source wireless device is maintained at the first switch, inserting into the packet a direction indicator, and forwarding the packet from the second switch to the first switch, the direction indicator identifying the packet as being transmitted towards the point of presence for the source wireless device to prevent a forwarding loop. An apparatus is also disclosed.
