Hi Sundar, Maybe the problem could be that you have to tell your br-int switch that the port that connects to enp1s0 is a trunk interface and carries VLAN 3.
Something like the following command issued in host 3 could do the job: ovs-vsctl set port enp1s0 trunk=3 Just in case it is useful, in VNX (Virtual Networks over linuX, http://vnx.dit.upm.es) site we have an example scenario using OVS and VLANs: http://web.dit.upm.es/vnxwiki/index.php/Vnx-tutorial-openvswitch In section 4 in that page you can find the ovs-vsctl commands that VNX tool issues to create the scenario and configure VLANs.
