Abstract
========
This document comprises the release notes for the SDN VPN feature contained in the Danube
release of OPNFV.
Important notes
===============
In the Danube 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.

Version change
--------------
Compared to the Colorado release, a new version of ODL including
several critical bugfixes is deployed. Together with the new BGP
stack, integration with Apex, the Horizon dashboards and bugfixes the
user has even more features available. New testcases were added to
functest to guarantee functionality.

Document changes
~~~~~~~~~~~~~~~~
Reason for version
------------------
Feature additions
~~~~~~~~~~~~~~~~~
SDN VPN adds the possibility to create and associate BGP/MPLS based
Virtual Private Networks (VPNs) through the OpenStack Neutron BGPVPN
API extension.
A new installer based on Apex is provided.
The Horizon dashboard for the OpenStack Neutron BGPVPN API extensions
is available.
Bug corrections
~~~~~~~~~~~~~~~
- Several bugs in ODL VPN Service have been fixed in this release.
- Floating IP is now working and tested in functest, relevant Tempest
tests have been enabled.
- Performance issues have been rectified and the relevant tests have
been enabled again.
- Yardstick testcases have been enabled again.
Deliverables
------------
Software deliverables
~~~~~~~~~~~~~~~~~~~~~
- Fuel plugin for OpenStack BGPVPN
- Changes to ODL Fuel plugin to activate the NetVirt Karaf features
and to apply the appropriate configuration. Also changes to
implement integration with 6Wind Zrpcd and Quagga.
- Changes to Apex to enable a BGPVPN deployment.
- Integration of VPN Service functional tests and BGPVPN API tests into Functest framework.
- Enabling performance tests in Yardstick.
- Changes to 6Wind Zrpcd to enable integration with Apex.
Documentation deliverables
~~~~~~~~~~~~~~~~~~~~~~~~~~
- Paragraph on SDN VPN feature for platform overview
- Configuration guide
- User guide
- Release notes (this document)
Known Limitations, Issues and Workarounds
=========================================
System Limitations
------------------
Known issues
------------
Moving to the new NetVirt has caused a regression in which a subnet
cannot be both attached to a Router and Network associated to a VPN.
This has been worked around in the tests and the upstream bug is being
tracked [0].
OpenStack NAT does not work. Instances created in subnets that are connected to
the public network via a gateway should have external connectivity. This does
not work and can be worked around by assigning a Floating IP to the instance [1].
For Apex the peering with the virtual Peer is not working due to limitation
of apex networking.
Workarounds
-----------
The router/network association mutual exclusivity is worked around
by not network associating subnets attached to routers.
The NAT issues are worked around by assigning floating IPs to VMs that require
external connectivity.
Test results
============
The deployment scenarios have successfully deployed in OPNFV CI many
times and all Functest tests (general and feature specific) are
passing.
