Overview
This tutorial shows how to use VPP lite to build a simple/toy IP4 LISP overlay on an Ubuntu host using namespaces and af_packet
interfaces.
Requirements
- Ubuntu host
- ODL Beryllium
Topology
add pretty pic
Setup
This section explains how to build VPP lite and walks through the host, vpp and ODL configs
Build VPP lite
Assuming this is done in a vagrant vm:
cd vagrant/vpp export PLATFORM=vpp_lite make build
More details on vpp-lite and other alternative builds can be found VPP/Alternative_builds.
Host
Create namespace and set up interface in linux

vpp1 config
Create and configure the LAN and WAN facing af_packet
interfaces
- Create LAN facing
host-vpp1
and WAN facinghost-intervpp1
interfaces - Set
6.0.2.1/24
and6.0.3.1
as their respective IP4 addresses
Enable and configure LISP-GPE:
- Set WAN facing interface
host-vpp1
as locator (underlay attachment point) - Set LAN facing prefix
6.0.2.0/24
as a local EID (End-host ID - overlay address) - Configure map-server address
6.0.3.100
create host-interface name vpp1 set int state host-vpp1 up set int ip address host-vpp1 6.0.2.1/24 create host-interface name intervpp1 set int state host-intervpp1 up set int ip address host-intervpp1 6.0.3.1/24 lisp gpe enable lisp locator-set add ls1 iface host-intervpp1 p 1 w 1 lisp eid-table add eid 6.0.2.0/24 locator-set ls1 lisp map-resolver add 6.0.3.100
vpp2 config
Create and configure the LAN and WAN facing af_packet
interfaces
- Create LAN facing
host-vpp2
and WAN facinghost-intervpp2
interfaces - Set
6.0.4.1/24
and6.0.3.2
as their respective IP4 addresses
Enable and configure LISP-GPE:
- Set WAN facing interface
host-vpp2
as locator (underlay attachment point) - Set LAN facing prefix
6.0.4.0/24
as a local EID (End-host ID - overlay address) - Configure map-server address
