17 This document comprises the release notes for the SDN VPN feature contained in the Gambia
23 In the Gambia release, SDN VPN only supports ODL as a backend. Make sure to always deploy
24 SDN VPN and ODL together. Make use of deployment scenarios including the SDNVPN feature such
25 as os_odl_bgpvpn_{ha|noha}.
30 SDN VPN adds the possibility to create and associate BGP/MPLS based
31 Virtual Private Networks (VPNs) through the OpenStack Neutron BGPVPN API
32 extension. See the scenario description and the user guide for details.

112 Known Limitations, Issues and Workarounds
113 =========================================
122 Moving to the new NetVirt has caused a regression in which a subnet
123 cannot be both attached to a Router and Network associated to a VPN.
124 This has been worked around in the tests and the upstream bug is being
125 tracked [0]_ and [2]_.
127 NAT for a VM which is in a private neutron network does not work. Instances
128 created in subnets that are connected to the public network via a gateway
129 should have external connectivity. This does not work and can be worked
130 around by assigning a Floating IP to the instance [1]_.
132 Currently we observe non-deterministic failures of individual tests within the
133 SDNVPN section of the Functest suite, which are not reproducible in the development
134 environment. In a development environment all Functest tests are successful.
135 Sporadic failures have been observed in test cases 4 and 8. Furthermore, the
136 check of bgpd service running on Controller node, in test case 3, has a constant
137 failure trend for Apex environment.
142 The router/network association mutual exclusivity is worked around
143 by not network associating subnets attached to routers.
145 The NAT issues are worked around by assigning floating IPs to VMs that require
146 external connectivity.
151 The deployment scenarios have successfully deployed in OPNFV CI many
152 times and all Functest tests (general and feature specific) are passing,
153 with the exceptions described above.
