Hi. There is a bit of misunderstanding here. 'resubmit' is an action and Open vSwitch extension. 'goto_table' is an OpenFlow instruction (not action). So, with ovs-ofctl you're adding a 'resubmit' action, but with Ryu you're trying to add 'goto_table' instructions. 'goto_table' must be the last instruction in a flow, so you can not add more than one of them. The 'resubmit' extension is more flexible. I hope that helps. Best regards, Ilya Maximets. _______________________________________________ discuss mailing list disc...@openvswitch.org https://mail.openvswitch.org/mailman/listinfo/ovs-discuss
