I am going to close this as Stein is very old. If you can reproduce on a
newer release please re-open with more information.

Title:
Neutron - Stein - Having two external networks will prevent the router
from being created.
Status in neutron:
Won't Fix
Bug description:
I am seeing an issue where creating two networks marked as external
will prevent a Neutron router from spawning on the Controllers. Ports
attached to those networks will be shown as down.
Environment:
- Openstack Stein.
- Deployed through Kolla.
1) One network+subnet (EXT) marked as external with X vlan configured on
physnet1. This is expected to be used as the SNAT for a router and floating
IPs. Not marked as shared.
2) One network+subnet (PROV) marked as external with Y vlan configured on
physnet1. Not currently in use on any qrouters.
3) Create one router with SNAT and the external network set as the EXT
network.
4) The router is created within Openstack but is never created on the
Controllers namespaces. All port are marked as down.
5) I've attached the logs.
6) If I clear the gateway from the router, the router is spawned and the
interfaces come up.
7) If I re-add the gateway with the EXT network. The router goes down and the
interfaces are deleted.
