In the dataplane yes. However, from the OF view, each GRE tunnel is still assigned a different OF port. > > root@:/home/akabra# ovs-dpctl show > system@ovs-system: > lookups: hit:331101 missed:1090 lost:0 > flows: 1 > masks: hit:584458 total:1 hit/pkt:1.76 > port 0: ovs-system (internal) > port 1: ion1 (internal) > port 2: gre_sys (gre) > > Can somebody tell me why this change was done?
