By not “working” do you mean you cannot get the plugin to work in a multi-provider environment? Multi-provider solutions have been tabled until Juno, where more discussion is occurring on what is the best way to support different service providers.
<div>
<div><br>
</div>
<div>However, you should be able to get the plugin to work as the “sole” VPN service provider, which is what the Cisco solution does currently. You can look at how I’ve done that in the cisco_ipsec.py modules in the service_drivers and device_drivers directories,
under neutron/services/vpn/.</div>

Is there any other
patch trying to solve the problem? Is there any way to workaround the issue to get a VPNaaS plugin working?

<div dir="ltr">I'm following the change you pointed a week ago. It seems that it is working now, and will be eventually approved soon. I will be happy when it is approved.

<div>Anyway, I need more information about how to develop a service driver and a device driver for VPN plugin. I realize doing reverse-engineering that I need and RPC agent and and RPC between them to communicate and use a kind of callbacks to answer. Where

<div><br>
</div>
<div>I want to develop a vpnaas implementation. It seems that since Havana, there are plugins, services and device implementations. I like the plugin and his current API, then I don't need to reimplement it. Now I want yo implement a vpnaas driver, and I see
I have two main parts to take into account: the service_drivers and the device_drivers. IPsec/OpenSwan implementation is the unique sample I've found.</div>
<div><br>
</div>
<div>I'm using devstack to test my experiments.</div>
<div><br>
</div>
<div>I tried to implement VpnDriver Python class extending the main API methods like IPsecVPNDriver does. I placed basic implementation files at the same level of IPsec/OpenSwan does and configured Neutron adding this line to /etc/neutron/neutron.conf file:</div>
<div><br>
</div>
<div><code>service_provider = VPN:VPNaaS:neutron.services.vpn.service_drivers.our_python_filename.OurClassName:default</code><br>
</div>
<div><code><br>
</code></div>
<div><code><span style="font-family:arial,helvetica,sans-serif">I restarted Neutron related services in my devstack instance, but it seemed it didn't work.</span></code></div>
