Hi,
I tried your topology script and your app on my environment,
the ARP broadcast storm has occurred.
I have not investigated why further, please confirm your app
(multipath.py) can cooperate with simple_switch_stp_13.py.
For example, simple_switch_stp_13.py installs the flows for
L2 switching into Table 0 with priority 0 by the default and
your app (multipath.py) seems to install the flows into the
same Table with the same priority.
I guess these apps have some logical conflicts in the flow
table...
Thanks,
Iwase
