Thanks for your reply Jesse. >>You created an L3 tunnel but OVS is an Ethernet switch, so it doesn't >>know how to send traffic over it OVS can work on L2/L3/L4, then why it doesn't knows how to send traffic over it ? Do you mean that the tunnels created using OVS are L2 tunnels ? I understand that when we create tunnels using OVS, we specify remote and local IPs. Aren't these L3 tunnels.

I'll have a look at it. I came across the below link while googling http://t32940.network-openvswitch-development.opennetworks.info/openswitch-and-gre-kernel-module-t32940.html The link says that OVS GRE tunnels support Ethernet encapsulation. But again, we give remote and local IP information in OVS GRE tunnels, so aren't these IP encapsulated tunnels. I am new to tunneling so some of my questions might sound silly. But, I'd be glad if you can give me some pointers.
