[Bug 2088286] [NEW] external port created by neutron-vpnaas with ovn driver is not fully configured
Public bug reported:
Hello
We are deploying OpenStack/Neturon with OVN, BGP (ovn-bgp-agent) and
VPNaaS and we encountered a problem - because of incomplete
configuration of VPN services external port bgp agent isn't announcing
it's address.
Summary: external port created by neutron-vpnaas with ovn plugin/driver
is not fully/properly configured and because of this ovn-bgp-agent won't
announce/publish/configure routing path for this address.
$ /var/lib/kolla/venv/bin/neutron-ovn-vpn-agent --version
neutron-ovn-vpn-agent 24.0.2.dev42

And now it's possible for tunnel to connect.
I tried to identify code of ovn driver/plugin in neutron-vpnaas
responsible for external port allocation, but I wasn't able to find it.
