Switches are not connected in the topology page of DLUX UI

Hi, I have deployed One Openstack Controller with ODL Controller and One Openstack Compute Node through Fuel. In the both hosts, I am able to see VxLAN tunnel ports for 'br-int' bridge. But, when I saw the Topology page in the DLUX UI (http://<odl_controller>:8181/index.html#/topology), I am able to see two Openflow switches. But, connection between these switches is not showing. I am able to PING the Controller and Compute machine from one another. Because of this, VM's are not pinging through VxLAN tunnels. Can anyone give me a hint, where could be the issue?

Following are the details: Openstack Controller:
