I have two Ethernet segments : Host A <-> Switch 1 <-> Host D <-> Switch 2 <-> Host B Host D has two ports, one in each segment. A and B are in the same subnet and will run ping, netperf, wget... If I use OVS-DPDK on Host D, it works fine. But OVS is way too complex for what I want. If I use l2fwd from DPDK, it does not work. The broadcast ARP does not make it through. Is there a simple example of packet forwarding that is supposed to work ? I have no need for L2 learning or anything fancy, just forwarding packets between the two ports. Regards, Jean
