Table of Contents

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.
