Hi,
I am working on LINC testbed set-up. If I use the of_controller_v4.erl,
which is available in the scripts folder of LINC-Switch, the Ping command
works immediately. But if I use Ryu controller with l2_switch_v1_3.py, it
takes time for Ping to work. As soon as the Ping command is issued from
VM1, It is showing the ARP request and ARP reply on the controller output,
but on the VM1 console, destination not reachable message will be shown for
some time. If I check with arp -a in VM1 the Hw address of VM2 is not
available. It takes time for the ping to work. May I know the reason for
that. Every time I make the machines to ping using the of_controller_v4.erl
to make arp cache to have the other machines HW address and use
remove_v1_3.py to remove the flow entries before using the Ryu controller.
Am I missing anything. Why the arp reply is not reaching the machine which
initiates the request with the l2_switch_v1_3.py immediately.
Thanks
Gandhi
