Why VXLAN Needs EVPN: Solving Data Center Networking Challenges

Sun, 17 Nov 2024 15:48:46 +0800

With the rapid growth of cloud computing and virtualization, traditional enterprise networks are showing limitations in scalability, flexibility, and reliability. To overcome these challenges, overlay networks emerged, allowing logical networks to be built over physical infrastructure.

Among these technologies, VXLAN (Virtual Extensible LAN) has become widely adopted for its scalability and isolation. However, VXLAN alone lacks a proper control plane, relying instead on inefficient flood-and-learn behavior. This is why EVPN (Ethernet VPN) is essential—it provides the intelligence VXLAN needs for modern data centers.
