It started to work , after i modified this code:<br />
<br />
def _fetch_external_net_id(self, force=False):<br />
"""Find UUID of single external network for this agent."""<br />
self.conf.gateway_external_network_id = ''<br />
#if self.conf.gateway_external_network_id:<br />
# return self.conf.gateway_external_network_id<br />
return self.conf.gateway_external_network_id<br />
<br />
from https://github.com/openstack/neutron/blob/master/neutron/agent/l3/agent.py<br />
<br />
Looks like, that respective option is not being read correctly from the respective configuration file.<br />
<br />

<br />
I am trying to install Openstack Stein on a single node, with multiple external networks (both networks are also shared).<br />
However, i keep getting the following error in the logs, and the router interfaces show as down.<br />

<br />
<br />
I have set these parameters to empty, as mentioned in the docs.<br />
<br />
/etc/neutron/l3_agent.ini<br />
<br />
gateway_external_network_id =<br />
external_network_bridge =<br />
interface_driver = openvswitch<br />
<br />
I tried linuxbridge-agent too,but i could not get rid of the above error.<br />
<br />
openstack port list --router router1<br />

<br />
However it does work when i have just one external network<br />
<br />

<br />
May i please know, how to get the above working.<br />
I have seen multiple articles online that mention that this should be working, however i am unable to get this to work.<br />
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.<br />
<br />
<br />
Thank you,<br />
Lohit<br />
