Hi, Thank you very much for the reply. I haven't explicitly created VLAN 21 on the physical machine. As both the physical machines are connected by crossover cable through eth0, I did the following:
ovs-vsctl add-port br0 eth0 ifconfig eth0 0 ifconfig br0 192.168.5.5 netmask 255.255.255.128 I assumed by adding port eth0 to br0 it would be a trunk port which allows all traffic. I also tried to add the port in the following way: ovs-vsctl add-port br0 eth0 trunks=21 and tried to send only VLAN 21 traffic. It was still not working. Could you please let me know if I am missing something? How should I create a VLAN 21 on the physical machine? Is it by using 'vconfig' and create interfaces? It would be very helpful if I have a little more details. Thank you, Anisha.
