### Conclusion
-VXLAN provides a robust method for extending Layer 2 networks over Layer 3 infrastructures. When properly configured, it enables flexible, scalable, and secure network designs across geographically dispersed locations. This setup is especially beneficial in environments where virtualization and containerization are heavily used, allowing seamless connectivity across various hosts and clusters.
