<div dir="ltr"><div><div><div>hi all:<br><br></div>I use floodlight as the network controller with openstack neutron. I configure neutron in GRE mode, so there are br-int and br-tun bridge.<br><br>I have to set controller for both br-int and br-tun, but after I restart neutron-openvswitch-agent, the br-tun's controller is gone, but br-int's controller remains.<br>
<br></div>I don't know whether this situation is normal, everything is OK except the gone bridge controller setting.<br><br>Since br-tun has no controller, floodlight thought two br-int bridges in two compute nodes are isolated, but actually they are connected throught br-tun bridge, the topology is br-int(node1)--br-tun(node1)----GRE tunnel---br-tun(node2)-br-int(node2)<br>
