I am trying to build the following network topology in NOX
|----------| |------------------| |-----------------| |----------| | End1 |-----------| Openflow1 |----------------------------| Openflow2 |---------| End 2 | |----------| |------------------| |-----------------| |----------| Both of the Openflow switches are connected to the Nox-Controller My .conf file is: SWITCHES="s1 s2 s3 s4 s5" s2_SLIRP=yes s4_SLIRP=yes VMS="end1 openflow1 openflow2 end2" end1_NETS=s1 end2_NETS=s5 openflow1_NETS="s1 s2 s3" openflow2_NETS="s3 s4 s5" end1_KERNEL=kernel.bin end2_KERNEL=kernel.bin openflow1_KERNEL=kernel.bin openflow2_KERNEL=kernel.bin Now, I have a few doubts 1. When I do dhclient on Openflow1 and Openflow2, both of them get the same ip 10.0.2.15 on eth1. Is this right? Since they are different interfaces, how can they use same IP? 2. How do I connect the two switches? I am doing ./dpctl addif nl:0 eth0 to connect Openflow1 to End1 ./dpctl addif nl:1 eth0 to connect Openflow2 to End2 3. Can pyswitch allow me to send packets from End1 to End2? Regards, -- Rohit Manohar Graduate Student North Carolina State University Raleigh, US.
