Overview
This tutorial shows how to use VPP lite to build a simple/toy LISP overlay on an Ubuntu host using namespaces and af_packet.
Requirements
Ubuntu host
ODL Beryllium
Topology
add pretty pic
Setup
Host and vpp configs
Host
Create namespace and set up interface in linux

vpp 1 config
This is the configure script for vpp1. First create and configure the client and wan facing af_packet interfaces and afterwards enable and configure LISP-GPE. The WAN facing interface is used as locator (underlay attachment point), the LAN facing prefix is configured as a local eid (overlay address) and finally the map-resolver address is added.
