Hey,
I installed Routeflow and mininet in separate VMs. I was able to successfully test rftest1. But when I was testing rftest2, I was not able to ping between hosts. I can ping from host to any switch and switch to any other switch. when I looked into the routing table in a switch, it was not able to get the route to network between hosts and switches. please help me get through this. Both VMs have host-only adapters.

mininet> pingall

*** Ping: testing ping reachability

h4 -> X X X
