Explanation

An IP fabric does not support Layer 2 protocols: A pure IP fabric is designed to work primarily at Layer 3 and does not require Layer 2 protocols like spanning tree or VLANs for operation. It focuses on IP-based routing and forwarding, and Layer 2 protocols are not typically used within the fabric itself. Devices in an IP fabric function as Layer 3 routers: In a pure IP fabric, devices (typically leaf and spine switches) operate primarily as Layer 3 routers. They are responsible for routing IP traffic across the fabric, with VXLAN or other tunneling technologies used for overlay and
