Dear Iwase,
Thank you, but I am not working on mininet and OVS. All the 6 switches are
connected to RYU controller each switch ports information is available.
Therefore, the only link between sw5 and Sw6 is not discovered. Please, let
me how to debug this problem and I contacted GEANT Testbed Service also and
they suggested me to look into RYU Controller configuration or It might be
RYU Bug.
if you needed it, I can give accesses to the portal to login and check the
problem.
Please, help me out. As it is very Important me as I am working my Master's
Thesis.
Thanks
Hari Raghavendar Rao
