Abstract: Fast roaming across a network fabric may be provided. A route device may receive location information corresponding to a client device in response to roaming by the client device from a first access point connected to a first network device to a second access point connected to a second network device. The first network device and the second network device may comprise fabric edge nodes on the fabric network. The first network device and the second network device may be ones of a plurality of network devices in the fabric network. On detecting the roaming of the client device, the route device may be updated with the new location, and then the route device may send, to the plurality of network devices in the fabric network, the location information corresponding to the client device.
