Before you can configure Locator/ID Separation Protocol (LISP), you will need to determine the type of LISP deployment you intend to deploy. The LISP deployment defines the necessary functionality of LISP devices, which, in turn, determines the hardware, software, and additional support from LISP mapping services and proxy services that are required to complete the deployment. LISP configuration requires the datak9 license. https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/iproute_lisp/configuration/xe-3s/irl-xe-3s- book/irl-overview.html
