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: A method for establishing a partitioned fabric network is described. The method includes establishing a fabric network including a plurality of border nodes to couple the fabric network to one or more external data networks and a plurality of edge nodes to couple to the fabric network to one or more hosts. The method further includes defining a plurality of partitions of the fabric network. The method further includes registering each of the plurality of partitions with a corresponding one of the plurality of border nodes and with each of the plurality of edge nodes.

Abstract: In one embodiment, a router includes processors and computer-readable non-transitory storage media coupled to the processors including instructions executable by the processors. The router may store at least one virtual prefix and an associated aggregation threshold. The router may register, with a mapping database of an overlay network, ownership of individual prefixes served by the router. The router may determine an amount of prefixes served by the router that are within an address space of the virtual prefix. The router may register, based on a determination that the amount of prefixes satisfies the aggregation threshold, ownership of the virtual prefix with the mapping database of the overlay network. The registration of the virtual prefix may cause ownership of one or more of the registered individual prefixes served by the router that are within the address space of the virtual prefix to be deregistered.

Abstract: In one embodiment, a supervisory device designates a particular networking device among a set of networking devices as a seed device and one or more interfaces of the seed device as discovery interfaces. The supervisory device coordinates, starting from the one or more discovery interfaces of the seed device, discovery of a Layer 2 topology of the set of networking devices, by designating one or more interfaces of a discovered networking device as discovery interfaces. The supervisory device converts, starting from at least one of the network devices farthest from the seed device in the Layer 2 topology and ending with the seed device, links of the Layer 2 topology into Layer 3 links, to form an underlay network.
