Public bug reported:

There is the ovn-bgp-agent project [1] that is a part of the Neutron
stadium. The goal of the project is to leverage FRR as a BGP speaker to
advertise routes for the OpenStack workloads. Starting OVN 25.03 [2]
core OVN supports dynamic routing that can replace the existing ovn-bgp-
agent project offering the same featureset.

This is an RFE to introduce new functionality to Neutron, so Neutron can
configure OVN norhtbound database with BGP capabilities. The goal is to
reach parity with ovn-bgp-agent with having no BGP related agent running
on the compute nodes. This will offer smoother integration of BGP and
Neutron and introduce less complexity, as all the BGP work will be
lifted by OVN.

As the solution is quite complex, this RFE will likely require a spec
where we can discuss implementation details.
