Thank you Sergey,
I’ve read the article in the link you’ve attached. I still don’t understand how ARP for the NH is resolved
i.e. the NH is connected via the dpdk interface so how can I know the remote NH mac ?
Best regards

Hello Avi.

OVS+DPDK supports vxlan tunneling in userspace. Packets are not reaching kernel. This requires endpoint IP rule being added to vxlan port.
More details can be found in related article https://github.com/openvswitch/ovs/blob/master/Documentation/howto/userspace-tunneling.rst.
As for OpenStack, Neutron needs endpoint IP to be set up in system. You can find appropriate implementation using https://github.com/openstack/networking-ovs-dpdk plugin for devstack or using Mirantis OpenStack based on Fuel.

Does the ovs-dpdk dupports vxlan in user-space ?
If yes what about arp and ip-fwding ?   this requires  ip-stack  (unless you implement this over the dpdk)
But ovs-dpdk is entirely running in user-space. Can someone explain ?
Best regards
