I have access in virtual sources of my University, i am trying to install openstack for learning purposes (version Queens) i made 2 virtual machines (one for controller & one for compute) but the university gives only one ipv4 per account so i made the controller as a router and i attached compute to it. Now i am in neutron service and i was wondering which option for network configuration is the best (https://docs.openstack.org/neutron/queens/install/controller-install-ubuntu.html (https://docs.openstack.org/neutron/qu...))

p.s i am using os ubuntu 16.04

Thank you!

No need for the controller to be a router. You connect compute and controller with private networks, which are easily implemented virtually.

To learn OpenStack, you should definitely explore both options 1 and 2.

If you are in University with limited access to network infastracture I think overlay network (with router and layer 3 agent) is the best, because I don't know if you switches allow you to pass vlans as segmentation method. From the other hand this way is more complicated and has same limitations like smaller MTU.

provider network is a better choice router is not very stable and harder to config to work
