<p>Some one posted a bug [1] for vlan arp responder and vlan l2population, which use the merged patch [2] for supporting the same thing in the ofagent</p>
<p> </p>
<p>So for DVR for vlan, I think we can continue with the bug fix above.</p>

<div>If those 200 subnets are VXLAN networks, i think it is a good idea, since L2population already propagate this configuration to OVS-Agent.<br>

<br>
One comment for VLAN network, since DVR also support in VLAN network and L2population is not necessary in it, what is your consideration in this case?<br>
