Beyond the Controller: Arista VESPA for Massive Campus Wireless Mobility

January 22, 2026

Are your campus WLAN architectures buckling under the pressure of extreme client density, IoT growth, and seamless user mobility?

For large enterprises and universities managing hundreds of thousands of devices across vast AP footprints, the limits of legacy controller-based designs are creating complexity, high OpEx, and service disruptions. Splitting the network into multiple mobility domains is no longer an acceptable solution for today's user expectations.

Join us to explore Arista VESPA (Virtual Ethernet Segment with Proxy ARP), the foundational architectural shift required for next-generation wireless mobility. We will demonstrate how Arista VESPA leverages standard data center principles (like EVPN) to enable a massive scale campus mobility domain across 500K clients
