Hi Sujay,
To the best of my knowledge it is not straightforward how to make OVS to
work with GRE tunnels. You might want do some research on the subject
before trying it.
BTW the examples that you have used might be outdated, I don't believe
that this is causing the problem I am just mentioning it for future
reference.
Good luck,
Niky
