Abstract: Systems, methods, and computer-readable storage media are provided for provisioning a common subnet across a number of subscribers and their respective virtual networks using dynamically generated network policies that provide isolation between the subscribers. The dynamic generation of the network policies is performed when a host (e.g. client) is detected (via a switch) as the host joins the computing network via virtual networks. This ability to configure a common subnet for all the subscriber virtual networks allows these subscribers to more easily access external shared services coming from a headquarter site while keeping the separation and segmentation of multiple subscriber virtual networks within a single subnet. This allows the Enterprise fabric to be more simple and convenient to deploy without making security compromises.

Abstract: Systems, methods, and computer-readable media for communicating policy changes in a Locator/ID Separation Protocol (LISP) based network deployment include receiving, at a first routing device, a first notification from a map server, the first notification indicating a change in a policy for LISP based communication between at least a first endpoint device and at least a second endpoint device, the first endpoint device being connected to a network fabric through the first routing device and the second endpoint device being connected to the network fabric through a second routing device. The first routing device forwards a second notification to the second routing device if one or more entries of a first map cache implemented by the first routing device are affected by the policy change, the second notification indicating a set of one or more endpoints connected to the second routing device that are affected by the policy change.

Abstract: Systems, methods, and computer-readable media for preserving source host context when firewall policies are applied to traffic in an enterprise network fabric. A data packet to a destination host from a source host can be received at a first border node instance in an enterprise network fabric as part of network traffic. The data packet can include a context associated with the source host. Further, the data packet can be sent to a firewall of the enterprise network fabric and can be received at a second border node instance after the firewall applies a firewall policy to the data packet. The data packet can then be selectively encapsulated with the context associated with the source host at the second border node instance for applying one or more policies to control transmission of the network traffic through the enterprise network fabric.

Abstract: The disclosed technology relates to a process for zero touch provisioning to provide cloud enablement of legacy computing devices. Specifically, the disclosed technology provides the ability to automate the process of connecting computing devices that may not originally have the capabilities to connect to the Internet so that the computing devices can be managed by a cloud network or be provided updates by the cloud network. The cloud enablement for computing devices is performed by modifying the computing device with hardware and software that would direct the computing device to establish secure communications with the cloud network without user involvement.

Abstract: A method including determining that network traffic being transmitted is unicast or multicast; mapping to which virtual network and locator address each host belongs; generating leaking data for unicast and multicast traffic, wherein the leaking data indicates that a first virtual network leaks traffic to a second virtual network; receiving a request from the second virtual network to receive traffic from a host in the first virtual network; determining, based on the leaking data and the type of traffic being transmitted, if the first virtual network leaks traffic to the second virtual network; if the first virtual network leaks traffic to the second virtual network, determining a locator address for the host in the first virtual network using the mapping data; and transmitting the locator address for the host to the second virtual network to enable traffic leaking from the host to the second virtual network is disclosed.
