[ovs-discuss] Testing GRE Tunneling in OVS

[Venkata Ravichandra Cherukuri]

Please correct me if I am wrong.

I have added flows already ( sorry for not mentioning it earlier.)

S1:
ovs-ofctl add-flow br0 in_port=1,actions=output:2 (where my logical port 1
is gre0 and logical 2 is eth1).

S2:
ovs-ofctl add-flow br0 in_port=1,actions=output:2 (where my logical port 1
is gre0 and logical 2 is eth1).

I am sure that this is not the perfect flow but this should atleast give me
partial result when I analyze the pcap.

Thanks for the quick revert.
