<div>Each DVR router has a unique MAC address that can be found in the Neutron DB in the dvr_host_macs table. Those will MACs will likely match what’s in the flow rules there.</div>

<div>
<div>hi guys.</div>
<div> In DVR mode, I have some questions about flows of table 9 in br-tun. I see these flows in br-tun:</div>
<div><br>
</div>
<div>
<div> cookie=0x9a5f42115762fc76, duration=392186.503s, table=9, n_packets=1, n_bytes=90, idle_age=247, hard_age=65534, priority=1,dl_src=fa:16:3f:64:82:2f actions=output:1</div>
<div> cookie=0x9a5f42115762fc76, duration=392186.447s, table=9, n_packets=0, n_bytes=0, idle_age=65534, hard_age=65534, priority=1,dl_src=fa:16:3f:76:6c:6f actions=output:1</div>
<div> cookie=0x9a5f42115762fc76, duration=392186.388s, table=9, n_packets=0, n_bytes=0, idle_age=65534, hard_age=65534, priority=1,dl_src=fa:16:3f:87:39:a3 actions=output:1</div>
<div> cookie=0x9a5f42115762fc76, duration=392186.333s, table=9, n_packets=0, n_bytes=0, idle_age=65534, hard_age=65534, priority=1,dl_src=fa:16:3f:93:41:45 actions=output:1</div>
</div>

</div>
<div>Port 1 is a patch interface which is connecting to br-int. </div>
<div><br>
</div>
<div>Question A: there are for mac addresses in these flows. But these mac addresses don't in my Neutron. What do they come from??</div>
<div><br>
</div>
<div>Question B: The action of each flow is output:1, why? Why put the packets to br-int?</div>
<div><br>
</div>

<div>Thanks</div>
