1. Set up the network toplogy:

   sudo mn --custom topo.py --topo mytopo 

2. Load the routes:

   mininet> source setup.mn 

3. Attempt some pings:

   mininet> serverA ping -c1 192.168.1.10 PING 192.168.1.10 (192.168.1.10) 56(84) bytes of data. 64 bytes from 192.168.1.10: icmp_seq=1 ttl=63 time=1.17 ms --- 192.168.1.10 ping statistics --- 1 packets transmitted, 1 received, 0% packet loss, time 0ms rtt min/avg/max/mdev = 1.170/1.170/1.170/0.000 ms mininet> serverB ping -c1 192.168.1.10 PING 192.168.1.10 (192.168.1.10) 56(84) bytes of data. 64 bytes from 192.168.1.10: icmp_seq=1 ttl=62 time=1.70 ms --- 192.168.1.10 ping statistics --- 1 packets transmitted, 1 received, 0% packet loss, time 0ms rtt min/avg/max/mdev = 1.704/1.704/1.704/0.000 ms
