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 managed by control plane of the fabric network to update routing locator entries associated with L2-VNID and L3-VNID in one or more databases when a client moves from behind a first switch to behind a second switch. In some embodiments, the control plane finds the L3-VNID from the L2-VNID. The L3-VNID is used to search for all IP addresses corresponding to a client-MAC. At least new routing locator value that is used in the routing locator entries is provided to the first switch, the second switch, and border nodes associated with the fabric network.

Abstract: Techniques are provided to manage how router advertisement messages are forwarded for ultimate wireless transmission in a wireless network. In one embodiment, a multicast router advertisement message intended for a virtual local area network is converted into individual unicast router advertisement messages directed to specific wireless mobile client devices that are part of that virtual local area network. In another embodiment, router advertisement messages are routed between controllers according to the current location of a wireless mobile client device. In still other embodiments, techniques are provided to minimize the volume of the router advertisement messages sent over a wireless network, and to proactively send a unicast router advertisement message to a mobile client device that has performed a handoff, without waiting for a router solicitation message.
