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

I have set these parameters to empty, as mentioned in the docs.
/etc/neutron/l3_agent.ini

interface_driver = openvswitch
I tried linuxbridge-agent too,but i could not get rid of the above error.
openstack port list --router router1

However it does work when i have just one external network
openstack port list --router router1

May i please know, how to get the above working.
I have seen multiple articles online that mention that this should be working, however i am unable to get this to work.
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.
