This is not a subject I know well. That said, it looks like OVS userspace doesn't currently support layer-3 GRE tunnels in an appropriate way. I mainly base this on the code in netdev_vport_is_layer3(), which considers only LISP ports to be layer-3 ports. _______________________________________________ discuss mailing list [email protected] https://mail.openvswitch.org/mailman/listinfo/ovs-discuss
