vxlan ports in Configuration datastore not created on device

Used Legacy Netvirt and stacked up 3 openstack nodes. Then performed operations like create Network/Subnet and instances.

At the end of operations, the instances failed to participate in communication. then noticed that it was not a full mesh.

From the output of ovs-vsctl show we notice that the vxlan ports in compute nodes are not connecting to control node.
