<div dir="ltr"><div><div><div>Cristian,<br></div>Thanks for responding so quickly. The instances should be attached to the internal network interface, which I can find on the network/compute node. It's under the namespace of the router for the project:<br>
<i>ip netns exec qrouter-4cff1882-1962-4084-9b48-cb1bcd048a4e ifconfig </i>shows two interfaces, one for the internal network and one for the external network.<br><br>The problem I think is that this router isn't reachable from my extra compute node. When I create the router, its namespace does not appear on the extra node.<br>
<br></div>And I am using dhcp, the quantum-dhcp-agent is installed on the network/compute node.<br><br></div>Brandon<br></div><div class="gmail_extra"><br><br><div class="gmail_quote">On Thu, Sep 26, 2013 at 9:57 AM, Cristian Falcas <span dir="ltr"><<a href="mailto:cristi.falcas@gmail.com" target="_blank">cristi.falcas@gmail.com</a>></span> wrote:<br>

The gre tunnels should take care of everything magically :).<br>

Where are the instances attached (that should be tap$id and source<br>
qbr$id)? Do you use dhcp?<br>
