<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 12pt;">Hello, Dina,
<div><br>
</div>
<div><span style="font-size: 12pt;">Thank you for your comments, i</span>t'll be good to discuss tricircle related topic in openstack-dev so that more people can be involved in if necessary, and keep the project transparent. So I copied the reply to openstack-dev@lists.openstack.org.<br>
<div><br>
</div>
<div>For L2VxLAN, the VNI identifiers will be allocated in central Neutron, and then same VNI segment will be used for local Neutron during get_network or get_port from Nova, the local plugin in local Neutron will query the network segment info. and persist
same uuid and VNI in local Neutron. But VxLAN based cross Neutron L2 networking has not started yet, the spec has not submitted for review yet, currently only VLAN based L2/L3 networking were implemented, supported features could be found in the release notes:https://github.com/openstack/tricircle/blob/master/releasenotes/notes/initial-release-notes.yaml<span style="font-size: 12pt;"> .</span></div>
<div><br>
</div>
<div> VxLAN L2 networking and VxLAN as the bridge network for L3 networking will rely on the patch for "formalize the tunnel termination point by adding it to the port binding data model" which is mentioned in "Eliminating L2pop as a mechanism driver" <a href="http://lists.openstack.org/pipermail/openstack-dev/2016-November/107061.html" target="_blank" style="font-size: 12pt;">http://lists.openstack.org/pipermail/openstack-dev/2016-November/107061.html</a></div>
<div><br>
</div>
<div>Before VxLAN L2 networking and VxLAN as the bridge network for L3 networking, this spec is being reviewed, <a href="https://review.openstack.org/#/c/396564/" target="_blank" style="font-size: 12pt;">https://review.openstack.org/#/c/396564/</a>, please
join the review to see whether it can meet your demands, especially for the cross Neutron networking models.</div>
<div><br>
</div>
<div>What is "<span style="font-family: Arial, sans-serif; font-size: 13.3333px;">RT parameters"?</span></div>
<div><span style="font-family: Arial, sans-serif;"><font size="3"><br>
</font></span></div>
<div><span style="font-family: Arial, sans-serif;"><font size="3">Tricircle supported L3 networking based on shared VLAN bridge network, you can refer to "</font></span><font face="Arial, sans-serif" size="3">6.6 L3 Networking across Neutron", but just as
what mentioned in the release notes, </font><span style="font-size: 12pt;"> only </span><span style="font-size: 12pt;">VLAN L2 network and shared VLAN as the bridge network for L3 networking are supported.</span></div>
<div><br>
</div>
<div>There are todo list for the usage documentation in ocata release, you are welcome to join the contribution, no matter documentation or source code or review.</div>
