This issue, we have seen on centos as well. Just for work around, ip link set promisc on eth0 #[eth0 --- PF interface] ip link set eth00 vf 0 spoofchk off #[give your vf id ] ip link set eth0 vf 0 trust on,
, But you will see other packet on vpp VF interface as well. Can you try with IPv6, you will see more surprises. :) //MJ *Regards*, Mrityunjay Kumar.
