No, I think the latter --controller just overrides the former. I don't
actually think there's a decent way to do this in Mininet. In earlier
versions, I think there was missing infrastructure. In Mininet 2, I think
there's still some stuff missing and you could almost make it work except for
I am using a mininet topology with a remote controller. However I want to
specify another redundant controller as a fallback option. Can I do as
follows
mn --custom topo-1sw-2host.py --topo mytopo --controller=remote
--ip=192.168.129.56 --ip=192.168.129.57.
Mininet seems to accept the above
