[pox-dev] Controller to split traffic by subnet

[Alison Chan]

Hello,

I'm having trouble designing my controller to split traffic by ip
subnet. The relevant controller code, topology setup, and pox log file
are in the linked gist:

https://gist.github.com/alis0nc/5639697

The topology and port assignnments look right as confirmed by 'net' in
mininet. Here is what I'm doing:

* start mininet by sudo mn --custom ~/mininet/custom/topo-ac.py
--topo=mytopo --controller=remote,ip=127.0.0.1,port=6633 --mac
* set up IP addresses on the nodes as follows:
    * h1: 10.0.0.1
    * h2: 10.0.0.129
    * h3: 10.0.0.2
    * h4: 10.0.0.130
* start PoX by pox/pox.py misc.my_controller 2>&1 | tee -i poxlog.txt
* mininet> h1 ping -c1 h2
* destination host unreachable
* wait about 5 seconds
* the errors start coming and don't stop

This is really my first OF controller past the tutorial so I apologise
if I'm doing something really really stupid... But any assistance
would be appreciated.

Cheers,
