Explanation

In Cisco SD-Access, the overlay architecture consists of three node roles: Edge Nodes (connect endpoints to the fabric), Border Nodes (connect the SD-Access fabric to external networks such as the internet, data center, or traditional campus), and Control Plane Nodes (run the LISP Map Server/Map Resolver function). Border nodes are therefore a core overlay component. Spine and leaf nodes (B, C) describe the physical underlay topology (a Clos fabric), not the overlay. Cisco DNA Center (D) is the management and orchestration platform that automates the fabric but is not itself an overlay node type.
