Hello,<br clear="all"><div><br></div><div>Is it possible to use GRE tunneling between compute nodes and VLANs with external networks?</div><div><br></div><div>Let me illustrate this. If we look at this reference picture from the docs <a href="http://docs.openstack.org/trunk/openstack-network/admin/content/connectivity.html">http://docs.openstack.org/trunk/openstack-network/admin/content/connectivity.html</a> .</div>
<div>The 'Data network' will use GRE tunnels and 'External network' would use VLANs for separating public networks. If this is really possible, I'm curious how to </div><div>properly configure that, so that provider networks are still available to VMs also. That would mean, tunneling VLANs over GRE, am I right?</div>
<div><br></div><div>Regards,</div>--janis<br>
