Thanks for your help. This patch (https://patchwork.ozlabs.org/patch/741524/ <https://patchwork.ozlabs.org/patch/741524/>) fixes the bug reported at : http://101.96.8.164/64.119.130.115/ovs/3d8e7354f5e981dee3301268fc498efcec6521e9/testsuite.dir/2180/testsuite.log.gz <http://101.96.8.164/64.119.130.115/ovs/3d8e7354f5e981dee3301268fc498efcec6521e9/testsuite.dir/2180/testsuite.log.gz> The other issue is that stp is timeout when running to the line on Joe’s machine. OVS_WAIT_UNTIL([ovs-appctl fdb/show br0 | grep '00:0c:29:a0:27:d1’]) OVS_WAIT_UNTIL([ovs-appctl fdb/show br1 | grep '00:0c:29:a0:27:d1’]) OVS_WAIT_UNTIL([ovs-appctl fdb/show br2 | grep '00:0c:29:a0:27:d1’]) Today, I try to reproduce it and fix it. More helpful info will be post here. Thanks for your help again. _______________________________________________ dev mailing list [email protected] https://mail.openvswitch.org/mailman/listinfo/ovs-dev
