Re: [pox-dev] host unreachable
Also, to add to what Sulabh advised, It would be nice if you can provide us with more info on what topology you have implemented. Apart from that, if you are using mininet vm , wireshark is inbuilt and you can fire it up, using ' sudo wireshark & 'that should help you see the packets and understand where the issue might be..

Re: [pox-dev] host unreachable
You can start pox with layer 2 learning algorithm. Try this: ./pox.py forwarding.l2_learning On Wed, Nov 13, 2013 at 1:42 PM, farshad tajedin wrote: > hi > when i run mininet by like "sudo mn --controller remote" and run > ./pox.py and ping h2 from h1 i get destination host unreachable, while > before it dose ping. can any body help me? > > -- > Best Regards > > Farshad Tajedin >

Are you trying to come up with some sort of general solution, or just making this happen on this particular topology? If it's the latter, you could probably do it with a handful of table entries installed "by hand". If it's the former, it's potentially considerably more complicated, depending on exactly how general you want it to be. -- Murphy
