Thank you Florin and Dave Florin - I can create tap in vpp and tap in namespace - but how to connect them like veth-pair ? how traffic transmitted from the namespace tap will be received on the vpp tap ? and viceversa
Dave - when i running iperf3 TCP i can see ~ 1000 pps , when i'm running UDP i see nothing (checking why...)
