title: Mesos, Docker and GRE Tunneling
body: <p>I'm running Mesos Cluster with docker as the container solution.
  I have tried Open vSwitch with dockers, with GRE Tunneling and VLANs across hosts.
  I'm trying to use this VLANs setup on Mesos - Still a WIP.</p>
  
  <p>Now my doubts are</p>
  
  <ol>
  <li><p>Is it possible to use GRE Tunneling on linux bridges - so that i can use the setup with docker0 bridge itself without using Open vSwitch.</p></li>
  <li><p>If GRE Tunneling is possible, what is the possibility of VLANs. Can docker can be configured to get launched on particular VLAN on the docker0 bridge.</p></li>
  <li><p>If Open vSwitch is the only solution for the above two - The ports created are not destroyed automatically, after the docker gets killed - like in docker0 bridge. Any solutions are ideas on this?</p></li>
  </ol>
  
  <p>Thank you very much in advance. </p>
