Patent number: 12021699Abstract: 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.Type: GrantFiled: April 21, 2023Date of Patent: June 25, 2024Assignee: Cisco Technology, Inc.Inventors: Sanjay Kumar Hooda, Muninder Singh Sambi, Victor Moreno, Prakash C.

Patent number: 12021750Abstract: Techniques for using more-specific routing to perform scalable Layer-2 (L2) stretching of subnets across hybrid-cloud environments. Routing tables in a public cloud may allow for routes that are more specific than the default local route, and the more-specific routes may be used to send all traffic to a dedicated, cloud router. The more-specific routes are set up for a VPC where a subnet resides such that the more specific-routes cover at least a portion of subnet range. The next hop for the more-specific routes point to the cloud router which is capable of doing host routing and segmentation extension. Thus, traffic originating from endpoints in a VPC is routed to the cloud router, and the cloud router determines whether the traffic is to be re-routed back to a destination endpoint in the VPC (or another cloud location), or sent to a destination endpoint residing in the on-premises site.Type: GrantFiled: August 5, 2022Date of Patent: June 25, 2024Assignee: Cisco Technology, Inc.Inventors: Rajagopalan Janakiraman, Suresh Pasupula, Manju Ramesh, Christophe Paggen, Huyen Trung Duong, Lukas Krattiger
