Yes, the network of a packet is encoded in the encapsulation. See "Tunnel Encapsulation" in ovn-architecture(7). (A packet that traverses a logical router passes through multiple networks. The one that appears on the wire would be that of the destination logical switch.) _______________________________________________ discuss mailing list discuss@openvswitch.org http://openvswitch.org/mailman/listinfo/discuss
