    I do not very understand this in dvr l2 agent (here https://wiki.openstack.org/wiki/Neutron/DVR_L2_Agent)
   " 3 After routing, the DVR router r1 puts the routed frame out of its green subnet interface. This frame is switched by the integration bridge towards the tunnel bridge along with tagging the frame with green network’s local-vlan tag.

4 The tunnel bridge on CN1, replaces the frame’s source mac address with a Unique DVR MAC Address of its node (one unique dvr mac address is assigned per compute node by the controller). The resulting frame is forwarded to CN2 by this tunnel bridge. Before forwarding, it also strips the local green-vlan tag and tunnels the frame with green-vni VXLAN id."

  How it is possible to use vlan for tenant network, and also use vxlan tunnel for physical host to communicate? I think they should keep the same.
