Which two functions is the Cisco SD-Access Border Node responsible for? (Choose two.)

Mapping users to virtual networks is primarily handled by the Control Plane node (LISP Map Server) in conjunction with network access control systems like Cisco ISE.

The SD-Access Border Node is responsible for advertising the Endpoint Identifier (EID) subnets, which represent the address spaces for users and devices within the fabric, to external routing domains via protocols like BGP, ensuring reachability from outside the fabric.

While Border Nodes do route IP traffic, this is a general function of many network devices; the question seeks specific, distinguishing roles of an SD-Access Border Node beyond basic routing.

The function of acting as an anycast Layer 3 gateway for endpoints within a virtual network is performed by the Fabric Edge Nodes, not the Border Node.

The Border Node functions as a LISP Proxy Tunnel Router (PxTR), handling the encapsulation and decapsulation of LISP-tunneled traffic when it traverses between the SD-Access fabric and external IP networks, thus providing seamless connectivity.
