Ryu does not use L3 info to transmit a packet. Ryu makes a flow table by a port number and MAC address (and tunnel id). Ryu transmit a packet to only the port of the same tenant, because Ryu knows the tenant (exactly a network of quantum/neutron) which an interface connected to each port of each switch belongs to. > > -- > Vasiliy Tolstov, > e-mail: [email protected] > jabber: [email protected] > > ------------------------------------------------------------------------------ > How ServiceNow helps IT people transform IT departments: > 1.
