[pox-dev] Fwd: Subnets and POX

The problem here is with the host configurations.  Check the routing tables.

For example, if you check the routing table on h1 (with "h1 route"), you'll see that it doesn't have any entry which can be used to route to 11.x.x.x.  The host never even tries to send the packet because it doesn't know where it should go.  You can fix it by, e.g., setting a default routing entry on each host (e.g., "h1 route add -net default h1-eth0").
