Abstract

This document comprises the release notes for the SDN VPN feature contained in the Brahmaputra release of OPNFV.

Important notes

In the Brahmaputra release, SDN VPN only supports ODL as a backend. Make sure to always deploy SDN VPN and ODL together. Make use of deployment scenarios including the SDNVPN feature.

Summary

SDN VPN adds the possibility to create and associate BGP/MPLS based Virtual Private Networks (VPNs) through the OpenStack Neutron BGPVPN API extension.

Release Data

Project sdnvpn
Repo/tag brahmaputra.3.0
Release designation Brahmaputra second stable release
Release date March 28, 2016
Purpose of the delivery Including ODL bugfixes

Version change

Compared to the Brahmaputra base release, a new version of ODL including several critical bugfixes is deployed.

Module version changes

ODL has been upgraded to Beryllium SR1. On top of Beryllium SR1, a number of bugfix patches are applied which will be contained in Beryllium SR2. The deployment procedure has been enhanced to take care of previously required manual post-deployment configuration.

Document changes

A slight readability improvement to the user guide has been made.

Reason for version

Feature additions

  • Changes to ODL Fuel plugin to activate VPN Service Karaf feature
  • Integration of VPN Service functional tests and BGPVPN API tests into Functest framework

Documentation deliverables

  • Paragraph on SDN VPN feature for platform overview
  • Configuration guide
  • User guide
  • Release noes (this document)

Known Limitations, Issues and Workarounds

System Limitations

The currently deployed system does not contain a BGP stack and hence is limited to providing connectivity within the domain controlled by one ODL instance (e.g. intra-DC communication). Addition of an open source BGP stack is planned for the Colorado release.

Feature specific Yardstick test cases have not been implemented, we plan to add these in Colorado

Known issues

The ODL VPN Service does not implement Floating IP, which is used extensively by Yardstick to run generic system tests, which do currently not pass for this reason.

Workarounds

Manual configuration of VPN Service internal transport between multiple compute nodes is needed to enable inter-node connectivity.

Test results

The deployment scenarios have successfully deployed in OPNFV CI many times and all Functest tests (general and feature specific) are passing.
