Abstract: The purpose of this paper is to provide network professionals with a common need to comprehend how to use VXLAN networks within their own organizations to release the entire potential of modern networking. Whilst interested network administrators shall acquire the most advantages from such content, the information contained within this research paper might be of use to each IT professional involved in network technologies. Aspects in this paper examine how VXLAN EVPN provides a solution to network challenges that have overwhelmed the entire industry for many years, and how to implement constructs that are usually observed in traditional networks thanks to this new technology. This research paper explores VXLAN EVPN, starting with an introductory stage, achieving a good understanding of terms and concepts as well as progressing via implementations through a single data center to several data centers. The following paper also refers design and the integration of Layer4-Layer7 network services, co-existence along with brownfield environments, operation, as well as maintain a VXLAN EVPN. At the conclusion of this paper, the reader will have a strong foundation of VXLAN EVPN and an understanding of real-world use instances that can be instantly used to help in the development of a strategy to effectively shift to next-generation data center with this new technology.

Keywords: VXLAN, EVPN, BGP EVPN, Layer4-Layer7 Services, MP-BGP EVPN, Multi-POD & Multi-Site, Cloud Networking, Datacenter networks, Network Virtualization.
