<p class="MsoNormal">As mentioned earlier in this thread there are few VM based L3 implementations already in neutron - from Cisco (CSR) and Brocade (Vyatta vRouter). Both extends off neutron L3 service-plugin framework. And they both have been decomposed in
the current Kilo cycle into stackforge. So all you need is another L3 service-plugin for openwrt hosted in stackforge. I don't see any framework level enhancements required to support this.<o:p></o:p></p>

I told here only my (maybe not good) idea that instead of openwrt as a<br>
service which will provide router functionalities in vm maybe better<br>
would be to provide some mechanism to make possibility to connect<br>
different vms which provide such router functionalities (something like<br>
service here).<o:p></o:p></p>
