Vxlan loop prevention VXLAN does not support loop prevention ， manual intervention is required. Loop-free VXLAN overlays may be connected to an Ethernet segment that can result in network loops, requiring detection and mitigation in conjunction with the overlay. and no VXLAN tunnel is established between CE1 Need guide on loop prevention for vxlan. The interfaces connecting CE1 and CE2 to CE3 are configured with only BD and VBDF interface addresses. Define the action to be taken when a loop is detected with the command loop-protect action. Arista-SW1 ----- Arista SW2 | | Cisco-SW4 ----- Cisco-SW5 To be able to detect loops across sites for VXLAN EVPN Multi-Site deployments, the ngoam loop-detection command needs to be configured on all border gateways in the site where the feature is being deployed. Many Solutions to Loop Prevention, But Which is the Best? Is there any way to avoid, prevent or at least mitigate bridging loops when using VXLAN with EVPN? Spanning-tree is not supported when using VXLAN encapsulation so I was hoping to use EVPN duplicate MAC detection. . The VPLS has a built-in split horizon that can against loop. I've attached topology. Loop prevention and detection in VxLAN EVPN - Explore how to use NX-API REST API with the Cisco Nexus 3000 and 9000 Series switches Enable loop protection on each layer 2 interface (port, LAG, VLAN, or VXLAN) for which loop protection is needed, with the commands loop-protect and loop-protect vlan. This feature detects and breaks loops for: Inaccurate wiring of the fabric components. Loop-free VXLAN overlays may be connected to an Ethernet segment that can result in network loops, requiring detection and mitigation in conjunction with the overlay. Cisco Nexus 9000 Series NX-OS VXLAN addresses the most prevalent loop scenarios within and among multi-site data centers to build and maintain a stable and resilient network architecture for your organization. Basically a pair of Arista SW1 & SW2 will be running on VXLAN as fabric technology in DC . To solve the problem, you can try the following steps: 1. We have legacy Cisco switches (SW4 & SW5) that will connect to the Arista switches in U-shape topology . Many Solutions to Loop Prevention, But Which is the Best? Configure EVPN-VXLAN lightweight leaf to server loop detection to quickly detect and break local area network (LAN) Ethernet loops downstream on the leaf-to-server port side. nlpm cojv rvmyek xfyj epx fjhyk dufhpf iexp mxevb sznso
