Routers work under Liberty and LinuxBridge just fine, in my experience, so don’t be too quick to give up on them. I promise you’ll have a tougher go at it, at this point, using another virtual machine as a router.</div>

<div>You have an IP configured on interface enp3s0, and I can’t tell what you have set as the physical interface mappings in the ML2/LinuxBridge agent config. On older email I see this:</div>

<div><font face="Calibri">If that’s still the case, you’re going to have a hard time. The LinuxBridge agent expects to put the enp3s0 interface into the respective brq-* bridge that corresponds to the public (flat) network. Once the interface is in the bridge,
you may lose connectivity to/from any address on that interface. At that point, your host will be unable to communicate with the router's gateway interface also in the bridge, and probably any external host. In this configuration, you may consider moving the
IP from enp3s0 to the brq-* bridge temporarily. That should work. Give it a try and let me know.</font></div>

<div>Conclusion. Neutron routers under Liberty (Linux Bridge) don't work. Please prove me wrong..... Moving on to manual router creation.<br>
</div>
1: How can I assign a fixed IP to an instance?<br>
</div>
2: If I add routes will they get used? I probably have to create a Port for every route (as Floating IPs do ).<br>
<br>

</span>I didn't mean to confuse you by assuming that you were running Open<br>
vSwitch. You don't have to run Open vSwitch, and some things do work<br>
differently when using Linux bridge.<br>
<br>
If your IP address is no longer on enp3s0, then that might be an<br>
indicator that you have a bridge subsuming enp3s0. In that case, I'm<br>
pretty sure that the physical_interface_mapping should be<br>
public:<bridge>. I spend a lot more time with OVS deployments, though.<br>
