[Rdo-list] Failing to deploy Mitaka on baremetal

Hi Marius,
your assumption is totally right: the external network is going to live
just on the controllers.

What I don't understand is why it's configured on the compute nodes. My
compute.yaml looks like this [1] and as you can see there's no external
network declaration and in any case "use_dhcp" is already set to false
for the main ovs_bridge. So why is this populating in any case?

Many thanks,
