Patent number: 10313224Abstract: Presented herein are techniques to enable seamless mobility of hosts (endpoints) between disaggregated Ethernet virtual private network (EVPN) domains that are connected with one another by an external network (e.g., a Wide-Area Network (WAN)). In one example, a leaf node in the first domain, which was previously connected to a host, receives updated routing information for the host. The leaf node performs a local host verification process to confirm that the host has moved and, in response to confirming that that the host has moved, the first leaf node sends a targeted host announcement message to the host in the second domain.Type: GrantFiled: September 13, 2016Date of Patent: June 4, 2019Assignee: Cisco Technology, Inc.Inventors: Sathish Srinivasan, Vrishabha Sikand, Shyam N. Kapadia, Lukas Krattiger, Massimiliano Ardica

Patent number: 10158564Abstract: A border leaf of a software defined computer network receives network traffic directed to a first endpoint from a second endpoint. The first endpoint is connected to the software defined network, and the second endpoint is external to the software defined network. If the border leaf determines that it does not have a stored network route for an active conversation between the first endpoint and the second endpoint, the border leaf determines a valid network route for the network traffic to reach the first endpoint. The border leaf stores the valid network route and forwards the network traffic to the first endpoint. The border leaf transmits a synchronization message to other border leaf nodes of the computer network. The synchronization message causes the other border leaf(s) to store the valid network route and an indication that the original border leaf is forwarding the network traffic in the active conversation.Type: GrantFiled: November 17, 2016Date of Patent: December 18, 2018Assignee: Cisco Technology, Inc.Inventors: Sathish Srinivasan, Vrishabha Sikand, Shyam N. Kapadia, Upendra N. Moholkar

Patent number: 9716628Abstract: A method is provided in one example embodiment and includes receiving from an orchestrator element for a new Virtual Routing and Forwarding element (“VRF”) created in a communications network a name of the VRF and interconnect identification; selecting a border element for the VRF; and creating in a database a VRF entry for the selected border element, the entry identifying a configuration profile for the selected border element. The method further includes forwarding a VRF create notification to the selected border element; and providing the configuration profile from the corresponding entry to the selected border element in response to a query to the database from the selected border element. The selected border element applies the configuration profile automatically to configure the selected border element.Type: GrantFiled: May 23, 2014Date of Patent: July 25, 2017Assignee: CISCO TECHNOLOGY, INC.Inventors: Vrishabha Sikand, Liqin Dong, Sachin Vijay Vishwarupe

Patent number: 9699066Abstract: A system and a method for providing conversational learning is implemented in a network environment. An exemplary method includes receiving a subnet route advertisement that includes an attribute that triggers glean behavior for routing decisions; and installing a subnet entry in a Forwarding Information Base/Adjacency (FIB/ADJ) table. The subnet entry includes a subnet associated with the subnet route advertisement and a corresponding glean adjacency. The corresponding glean adjacency is configured to trigger installation of a host entry associated with a host in an active conversation in a network.Type: GrantFiled: September 29, 2016Date of Patent: July 4, 2017Assignee: CISCO TECHNOLOGY, INC.Inventors: Shyam Kapadia, Vrishabha Sikand
