Patent number: 11799716Abstract: Techniques are described to provide layer 2 (L2) circuit failover in the event connectivity to an Ethernet Virtual Private Network (EVPN) instance is lost. For example, if one of multi-homed provider edge (PE) devices loses connectivity to the EVPN instance, the PE device may mark its customer-facing interface as down and propagate the interface status to the access node such that the access node may update its routing information to switch L2 circuits to another one of the multi-homed PE devices having reachability to the EVPN instance. In some examples, the plurality of PE devices may further implement Connectivity Fault Management (CFM) techniques to propagate the interface status to the access node such that the access node may update its forwarding information to send traffic on a different L2 circuit to another one of the multi-homed PE devices having reachability to the EVPN instance.Type: GrantFiled: March 31, 2022Date of Patent: October 24, 2023Assignee: Juniper Networks, Inc.Inventors: Channasangamesh S Hugar, Babu Singarayan, Sharmila Koppula, Soumyodeep Joarder, Sudhin Jacob

Patent number: 11349749Abstract: Techniques are described for facilitating node protection for Broadcast, unknown Unicast, and Multicast (BUM) traffic for a multi-homed node failure. For example, each VTEP (e.g., PE device) may advertise a protected VTEP address that indicates an IP address of a remote PE device that is to be protected in the event of a node failure. In the event a multi-homed PE device fails, the ingress PE device sends a BUM packet including the protected VTEP address for the failed node. When an egress PE device receives the BUM packet, the egress PE device determines whether the BUM packet includes the protected VTEP address and whether the egress PE device is operating as a backup designated forwarder (DF). If the BUM packet includes the protected VTEP address and the egress PE device is a backup DF, the egress PE device forwards the BUM traffic to the ESI.Type: GrantFiled: March 18, 2019Date of Patent: May 31, 2022Assignee: Juniper Networks, Inc.Inventors: Vikram Nagarajan, Kapil Arora, Robert W.

Patent number: 10771317Abstract: A first network device permits a bidirectional forwarding detection (BFD) session with a second network device. The first network device is a designated forwarder for a third network device, a first link is provided between the first network device and the third network device, the second network device is a backup designated forwarder for the third network device, a second link is provided between the second network device and the third network device. The first network device detects a link failure associated with the first link between the first network device and the third network device, and provides, via the BFD session, a BFD message to the second network device. The BFD message includes an indication of the link failure, and the BFD message is to cause the second network device to be a new designated forwarder for the third network device.Type: GrantFiled: November 13, 2018Date of Patent: September 8, 2020Assignee: Juniper Networks, Inc.Inventors: Soumyodeep Joarder, Kapil Arora, Sunil Kumar Malali, Vikram Nagarajan

Patent number: 10742542Abstract: A device may determine a link aggregation group (LAG) that aggregates links that includes a first group of links that connects the device to a first provider edge (PE) device and a second group of links that connects the device to the second PE device, where the first PE device and the second PE device are on an Ethernet virtual private network (EVPN) and are multi-homed PE devices for the device, and where the first PE device provides a local connection to a customer edge (CE) device for the device. The device may receive a message from the first PE device indicating that the first PE device lacks a connection with the EVPN, and may send, based on the message, traffic intended for the CE device via the first PE device and traffic intended for the EVPN via the second PE device and not the first PE device.Type: GrantFiled: October 22, 2018Date of Patent: August 11, 2020Assignee: Juniper Networks, Inc.Inventors: Wen Lin, Sharmila Koppula, Soumyodeep Joarder
