1.  Introduction

   The Locator/ID Separation Protocol (LISP) defines several network
   elements subject to be configured.  This document presents the YANG
   data models required for basic configuration of all major LISP
   [RFC6830]elements.  The models also capture some essential
   operational data elements as well.

2.  LISP Module

   This module is the base LISP module that is augmented in multiple
   models to represent various LISP device roles.
