Hi Aaron, thanks for you quick response.
So the whole L2 separation of the tenants is done via flow configuration. And the gre tunnel are merely there to connect the br-tun on the compute nodes with the br-tun on the L2 Node? Unfortunately I do not have a running Quantum installation, yet, therefore I cannot dump the flow. -martin On 05.03.2013 23:22, Aaron Rosen wrote: > Hi > > Response inline: > > On Tue, Mar 5, 2013 at 2:00 PM, Martin Mailand <[email protected]> wrote: >> Hi List, >> >> I hope this is ok to ask here.
