Abstract
A system and method for fast roaming in one or more enterprise fabric network. The fast roaming involves correlation operations performed in one or more databases to update routing values associated with L2-VNID and L3-VNID in the one or more databases when a client moves from a first network device to a second network device. In some embodiments, the control plane finds the L3-VNID from the L2-VNID.
