OvS-GRE Ping test

[attdone]

Hi Team,
I tried to arrange the setup for GRE test as specified in this document. https://github.com/bytedance/ovs-dpdk/blob/open-source/Documentation/howto/tunneling.rst

I am able to ping VM1 <-> VM2 and VM3<->VM4. But I am not able to ping VM1<->VM3 or VM1<->VM4 or VM2<->VM3 or VM2<->VM4.
Is there any changes to be made in the configuration to ping between VM1<->VM3 or VM1<->VM4 or VM2<->VM3 or VM2<->VM4. ?

did you test it using our version or just vanilla version?
I did not modify the GRE implementation of vanilla OVS there.
