Hi, Thanks for your reply. I'm not pinging the DPDK interfaces because I don't even have IP addresses for them as you mentioned , I'm trying to ping the hosts whose physical interfaces are directly physically plugged into that DPDK interfaces. So my use case is to connect two physical hosts through ovs with DPDK ports and this Ovs-dpdk is on a separate third host between the two communicating hosts. So do you have any idea how can I implement this use case?.

Typically DPDK NICS are unbound from the kernel driver and bound to either igb_uio or vfio userspace drivers in order to be used with a DPDK application. As such the NICS no longer have access to the Linux kernel stack, they have a MAC address but no IP as such to ping. If you are trying to ping the DPDK interfaces it would be expected that there would not be a response.
