Comment 1 for bug 1923592

Could you please elaborate what exactly is the topology you expect to be working?

I'm in now way an expert on routed networks, but so far I believed:

1) there should be a router that's attached to all segments of a (routed) network and
2) this router is not managed by Neutron:

"The Networking service does not provide layer-3 services between segments."
from here:
https://docs.openstack.org/neutron/latest/admin/config-routed-networks.html

Are these assumptions correct? If no, please correct them. If yes, then this could be an RFE.
