Hello,
I have the following topology and want to install rules in nodes (openvswitch nodes) to communicate with each other. N1(10.0.0.1) --- N2(10.0.0.2)--- N3(10.0.0.3) each node has another interface to connect to the controller directly. I want to write flow rules to help n2 to forward a packet from n1 to n3. So at first n1 sends a packetIn message to get the rules to communicate with n2 as following: (If the source of packet is n1 and the destination in n2, send the packet to the port) fm= of.ofp_flow_mod() fm.match.nw_src = “10.0.0.1” fm.match.nw_dst = “10.0.0.2” fm.actions.append(of.ofp_action_output(port= of.OFPP_FLOOD) event.connection.send(fm) Then in n2, I want to write a flow rule that if it receive a packet from n1 , forward that to n3. Could you let me know how should I write this rule? Thank you
