Abstract: Techniques for extended network configuration conversion and reconfiguration are described. A network controller proceeds through a set of extended network nodes in an extended network and reconfigures ports in at the various nodes from a first configuration to a second configuration while preventing network traffic looping and maintaining data and management traffic connection to the nodes during the reconfiguration.

Abstract: A cloud broker gateway interfaces with an enterprise network and one or more public cloud networks, including a first public cloud and a second public cloud. The cloud broker gateway receives a request for one or more computing resources from a tenant associated with the enterprise network, and directs the request to the first public cloud based on a brokerage policy for the tenant. The cloud broker gateway receives a response indicating the first public cloud cannot provide the one or more computing resources, and redirects the request to the second public cloud based on the brokerage policy for the tenant. The cloud broker gateway also establishes a hybrid cloud that provides access to the one or more computing resources between the second public cloud and the enterprise network.

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.
