Patent number: 11252074Abstract: A network device may receive, from an endpoint device, a first message that includes first endpoint identification information. The network device may be connected to the endpoint device via a plurality of links. The network device may receive, from another network device, a second message that includes second endpoint identification information. The network device may determine whether the first endpoint identification information corresponds to the second endpoint identification information. The network device may cause, based on determining whether the first endpoint identification information corresponds to the second endpoint identification information, a state of the plurality of links to be maintained or changed.Type: GrantFiled: March 25, 2020Date of Patent: February 15, 2022Assignee: Juniper Networks, Inc.Inventors: Vasudevan Venkatraman, Sushant Kumar

Publication number: 20210211372Abstract: The problem of looping at the egress of a transport network with a CE multihomed to a protected egress PE and a backup/protector egress PE can be avoided by (a) enabling the protector egress PE to distinguish between fast reroute (FRR) traffic coming from the protected egress PE and normal known unicast (KU) traffic coming from a PE of the transport network that is not attached to the same multihomed segment; (b) receiving, by the protector egress PE, known unicast data, to be forwarded to the CE; (c) determining, by the protector egress PE, that a link between it and the CE is unavailable; and (d) responsive to determining that the link between the protector egress PE and the CE is unavailable, (1) determining whether the known unicast traffic received was sent from the protected egress PE or from another PE of the transport network that is not attached to the same multihomed segment, and (2) responsive to a determination that the known unicast traffic received was sent from the protected egress PE, discardiType: ApplicationFiled: January 30, 2020Publication date: July 8, 2021Inventors: Wen Lin, Yi Zheng, SelvaKumar Sivaraj, Vasudevan Venkatraman, Prabhu Raj V.K., Channasangamesh S.

Patent number: 10476792Abstract: A device may receive, via a first message, first route information for directing network traffic for a network. The first route information may identify a media access control (MAC) route corresponding to a MAC address associated with a host device connecting to a subnet of the network. The first route information may fail to include Internet protocol (IP)/MAC binding information associated with the host device. The device may transmit a request for IP/MAC binding information associated with the host device. The device may receive a response, to the request for IP/MAC binding information, identifying the IP/MAC binding information. The device may advertise, via a second message, second route information for directing network traffic for the network based on receiving the response identifying the IP/MAC binding information. The second route information may identify the IP/MAC binding information associated with the host device.Type: GrantFiled: February 16, 2018Date of Patent: November 12, 2019Assignee: Juniper Networks, Inc.Inventors: Selvakumar Sivaraj, Wen Lin, Ravi Shekhar, Vasudevan Venkatraman

Publication number: 20170163530Abstract: Techniques are described for signaling aliasing capability between routers in a multi-tenant data center that uses VPNs, such as Ethernet VPNs. In the multi-tenant data center, two or more PE routers may be connected to a CE router by a multi-homed L2 segment in an all-active mode. Aliasing refers to the ability of a PE router to signal that it can reach a given multi-homed L2 segment even when the PE router has learned no MAC addresses over that multi-homed L2 segment. The PE routers on the multi-homed L2 segment advertise aliasing capability using a route advertisement on a per-L2 segment basis. When the multi-tenant data center uses global VPN identifiers, no additional information is needed by a remote PE to build an ECMP next hop to the PE routers that support aliasing, and transmission of a route advertisement on a per-VPN basis may be suppressed.Type: ApplicationFiled: February 17, 2017Publication date: June 8, 2017Inventors: John E. Drake, Wen Lin, Vasudevan Venkatraman
