    Hi Mathias,<br>
    <br>
    whether you have all corresponding bridges and patches between them
    as described in openvswitch_agent.ini using<br>
    <br>
    integration_bridge<br>
    tunnel_bridge<br>
    int_peer_patch_port<br>
    tun_peer_patch_port<br>
    bridge_mappings<br>
    <br>
    parameters? And make sure, that service "neutron-ovs-cleanup" is in
    use during system boot. You can check these bridges and patches
    using "ovs-vsctl show" command.<br>

      <br>
      maybe the port_filter causes still the problem? But how to disable
      it?
      <br>
      <br>
      Any other idea?
      <br>
      <br>
      Thanks and BR Mathias.
