A customer is using a legacy application that communicates at layer-2. The customer would like to keep this application working across the campus which is connected via layer-3. The legacy devices are connected to Aruba CX 6300 switches throughout the campus. Which technology minimizes flooding so the legacy application can work efficiently?
Correct Answer: B
EVPN-VXLAN is a technology that allows layer-2 communication across layer-3 networks by using Ethernet VPN (EVPN) as a control plane and Virtual Extensible LAN (VXLAN) as a data plane3. EVPN- VXLAN can be used to support legacy applications that communicate at layer-2 across different campuses or data centers that are connected via layer-3. EVPN-VXLAN minimizes flooding by using BGP to distribute MAC addresses and IP addresses of hosts across different VXLAN segments3. EVPN- VXLAN also provides benefits such as loop prevention, load balancing, mobility, and scalability3. References: https://www.arubanetworks.com/assets/tg/TG_EVPN_VXLAN.pdf
