[ovs-discuss] possible bug when falling back to the normal switch

Hi there, I am doing some test for my controller to handle the situation when some of the switches in the topology lose the connection to the controller. The part of the topology will be something like this: S1(DPID:11,port4)——(DPID:23,port3)S13(DPID:23,port2)—— (DPID:22,port3)S12 At first, all
