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"). -- Murphy On May 21, 2013, at 5:53 AM, Windhya Rankothge wrote: > I am very new to POX and I am trying to create communication between two > subnets. > ... > h1 = net.addHost( 'h1', ip='10.0.0.2' ) > h2 = net.addHost( 'h2', ip='11.0.0.2' ) > ... > I tried to run this topology with l3_forwarding example given in POX > > But the problem is I cant ping from h1 to h2.. > > Is there something more that I have to do, to make this work ?
