Bug Description
Tested on MOS 7.0 RC4
It was observed that ARP responder is disabled on 'Compute' nodes.
When DVR is enabled during deployment, ARP responder should also be enabled on all nodes holding 'Compute' role.
ARP responder in VXLAN/GRE deployments interacts with OVS, L2 population and tenant machines, preventing use of unnecessary broadcast frames, which could flood tenant networks and degrade network performance.

That is unfortunate miss. But we can't include it in 7.0
