Patent number: 11722395Abstract: A network device may receive a message. The network device may determine that the message includes return information indicating a path to an initial device that generated the message. The network device may modify the message by adding an upstream device identifier, wherein the upstream device identifier identifies a device from which the message is received. The network device may modify the message by adding an indication of whether the initial device is reachable by the network device using a segment identifier. The network device may provide the modified message to a downstream device.Type: GrantFiled: October 29, 2021Date of Patent: August 8, 2023Assignee: Juniper Networks, Inc.Inventors: Reji Thomas, Ronald Bonica

Patent number: 11516179Abstract: A network device in a network may determine a tentative network address for a network interface of the network device and may determine whether the tentative network address is duplicative of any one of the network addresses in the network. If the tentative network address is duplicative of a network address assigned to another network interface in the network, the network device may store an indication of the other network interface. In response to receiving an indication that a new network address is assigned to the other network interface, the network device may re-determine whether the tentative network address is duplicative of any one of the network addresses in the network. If the network device determines that the tentative network address is not duplicative of any one of the plurality of network addresses in the network, the network device may assign the tentative network address to the network interface.Type: GrantFiled: September 21, 2018Date of Patent: November 29, 2022Assignee: JUNIPER NETWORKS, INC.Inventors: Jimmy Jose, Pranavadatta D N, Reji Thomas
