Cisco Software Defined Access (SD-Access)

Cisco Software Defined Access is an example of VXLAN implementation with the LISP control plane.

VXLAN specific originated from Layer 2 LISP specification that aimed to introduce Layer 2 segmentation support to LISP.

LISP encapsulation can only support IP in IP over UDP encapsulation, whilst VXLAN can encapsulate the original ethernet header to perform MAC in IP encapsulation to support Layer 2 and Layer 3 overlays
