Hello,

You can start by looking at : https://docs.openstack.org/neutron/latest/ovn/gaps.html

You will find ovn documentation at : https://docs.ovn.org/en/latest/

For your routing questions with ovn, you'll find your response with ovn-nbctl which describes your network design and ovn-sbctl which will give you the mappings between your router ports and your physical chassis.

Hello.

I am going to deploy an openstack network for a DC. I would like to have some advice on choosing between them.

Could you show me some pros and cons between them? About OVN, I don't see many articles about it. And How can I check traffic routes via which GW, I can check this via ha_state with OVS

Thank you very much.
