Hmm... as far as I remember, l2_multi and l2_learning shouldn't behave differently in terms of L3. My memory is that with either of them, you're likely to run into the same problem -- it's not with POX or OpenFlow or anything -- it's with the hosts. The hosts will generally expect that they need a gateway to communicate with another subnet. If you reconfigure their routing tables so that they don't, things will work fine. IIRC, l3_learning gets around this by establishing "fake" gateways.
