thanks for the reply.. It is working for me aswelll.. For some reason it was not working before.. I did "sudo mn -c" and then repeated and it worked..
But I wanted to know when h0 pings h2 where exactly are these packets dropped? I wanted to keep track of the packets that come from other autonomous systems. How can i do this because i dont see any log message saying dropping packet so and so.. Do the packets from one autonomous systems reach the controller of the other autonomous system ?
