We have a hardware based F5 LTM with physical connections to Arista VLANs for both external (VIPs) and internal (backend servers). We can' have a direct physical connection to a VXLAN that has been setup. What is F5 best practice to load blanace servers on a VXLAN? Use static route? Use Network Virtualzation tunnel? Other method? Looking for Guidance and How to.
When you dont have access to the servers in VXLAN which have no direct physical access, or when we dont have specific or default routes for all the backend servers, its alwasys a good practice to try using AUTOMAP feature in SNAT section of a VIP configuration, instaead of using SNAT or SNAT address list , I would highly recommend to use AUTOMAP option.
Automap works great for assymetric routing, but can result in port exhaustion.
Please try setting this on one or few VIP and share your inputs.
Please refer below topics to help get more insights on the feasibility of using Automap feature in your design
