Hi Logan, Thanks for the reply. I have one more question. How we will check whether the tunneling is established or not? I have gone through lot of documents of gre setup and all are says that the "ovs-vsctl show" command will show the tunnel info. Also is there a doc to understand how the magic happens for tunneling.
