Absolutely agreed. We should verify that the full path routing still works as expected and then change the default configuration. Hi Martin, I am probably not fully appreciating the problem at hand too. My personal experience is that installing flow entries in the reverse direction

I notice that the routing module is behaving differently with NOX0.6 causing each switch en route to generate independent packet_ins, while NOX0.4 generates only 1 packet_in. This behavior incurs higher flow setup time. I have a topology of client - hpsw3 - hpsw1 - server . I performed a wget
