Currently OVS only allows Ethernet interfaces (ARPHRD_ETHER) to be added. A PPP interface presumably has PPP encapsulation (ARPHRD_PPP). I don't think that PPP encapsulates Ethernet frames (doesn't it typically encapsulate IP?). Since the Open vSwitch datapath only supports Ethernet, I don't think that it will work. (There are lots of assumptions above; I haven't checked my facts. I hope that someone will correct me if I am wrong.) _______________________________________________ discuss mailing list [email protected] http://openvswitch.org/mailman/listinfo/discuss_openvswitch.org
