<br>
<font face="sans-serif">The juno documentation says we can have multiple external networks with a single l3-agent. But never worked for me. So the way I could get it working is having two l3-agent files with different external networks. Starting one l3-agent the normal way and the second l3-agent from command "/usr/bin/python /usr/bin/neutron-l3-agent --config-file /etc/neutron/neutron.conf --config-file /etc/neutron/l3_agent2.ini --config-file /etc/neutron/fwaas_driver.ini"</font><br>

<font size="3" face="serif">Yes I did the same. But I've heard of people doing multiple l3 agent scenarios with success, Only that we are not getting replies. I am not sure If I am being paranoid, but I have a feeling that the community interaction these days are going down and corporate interactions are dominating. <br>

Hi,<br>
<br>
I've used this method successfully with two external networks, but only<br>
one l3 agent.<br>
