<div name="messageBodySection" style="font-size: 14px; font-family: -apple-system, BlinkMacSystemFont, sans-serif;">It started to work , after i modified this code:
<div><br /></div>
<div>
<div>def _fetch_external_net_id(self, force=False):</div>
<div> """Find UUID of single external network for this agent."""</div>
<div> self.conf.gateway_external_network_id = ''</div>
<div> #if self.conf.gateway_external_network_id:</div>
<div> # return self.conf.gateway_external_network_id</div>
<div> return self.conf.gateway_external_network_id</div>
</div>
<div><br /></div>
<div>from <a href="https://github.com/openstack/neutron/blob/master/neutron/agent/l3/agent.py">https://github.com/openstack/neutron/blob/master/neutron/agent/l3/agent.py</a></div>
<div><br /></div>
<div>Looks like, that respective option is not being read correctly from the respective configuration file.</div>

</div>
<div><br /></div>
<div>May i please know, how to get the above working.</div>
<div>I have seen multiple articles online that mention that this should be working, however i am unable to get this to work.</div>
<div>It is really important for us to have to have 2 external networks in the environment, and be able to route to both of them if possible.</div>
