I think this will be represented in neutron as a provider network, which has to be created by the overcloud admin, after the overcloud deployment is finished While based on Kilo, this was one of the best docs I could find and it includes config examples [1] It assumes that the operator created a bridge mapping for it when deploying the overcloud > > I think the answer here will be the same as for vanilla Ceph.
