Hi,
I have used simple_switch_13.py with simple topology that has two hosts and one
switch. I tried to ping h1 from h2.The first time I did that the controller
added the flow to the switch table. However, after the idle_timeout expired
(10s) the flow was deleted from the table. After that I tried to ping h1 from
h2, it return the " Destination Unreachable". To reconnect them, I must rerun
the controller.
Could anyone explain why this could happen?
Note: I tried the same experiment with simple_switch_12.py and it worked fine
without the need for doing th rerun of the controller.
