Which node performs the LISP Map-Server and Map-Resolver functions in the Cisco SD-Access network architecture?

The Control Plane Node in Cisco SD-Access serves as the central intelligence for the fabric, performing the critical LISP Map-Server and Map-Resolver functions. It maintains the database of all endpoint identities (EIDs) and their corresponding routing locators (RLOCs) within the fabric.

The Fabric Edge Node provides network access for endpoints and performs VXLAN encapsulation/decapsulation, acting as a LISP Tunnel Router (xTR), but it doesn't host the Map-Server/Resolver.

The Border Node connects the SD-Access fabric to external networks and is responsible for external routing, but it does not perform the primary LISP Map-Server/Resolver functions.

An intermediate node is a generic term and not a specific role in SD-Access that performs LISP Map-Server/Resolver functions.
