Oh, sorry, I just paste a wrong log actually my bridge has different name with port.

Hi Frank, You can't name a port the same name as your bridge, as a bridge always explicitly has an internal interface with the same name as the bridge, and all ports must have different names. Try naming your GRE port differently, e.g. test2.

I did set different GRE keys for tunnels. I google and get some articles said it's possible to create multiple GRE tunnels with same src/dst. I am curious what technical barrier prevents our doing since GRE key is an natural tag to distinguish different tunnels. BTW: when the interface created failed, ovs-vsctl also returns a uuid as if it succeeds. This is very puzzle, the real result in log is: " Dec 30 14:40:06|04201|bridge|INFO|created port test on bridge test Dec 30 14:40:06|04202|bridge|WARN|could not create iface test: File exists Dec 30 14:40:06|04203|bridge|WARN|bridge test: port test has no interfaces, dropping " cloud we have more graceful way to report such failure? thank you. _______________________________________________ discuss mailing list [email protected] http://openvswitch.org/mailman/listinfo/discuss_openvswitch.org
