neutron designate DNS dns_domain assignment issue

[Satish Patel]

I have deployed openstack using openstack-ansible (ussuri on centos8) I have integrated designate with neutron and trying to verify my setup so i did following.

# Mapping network with dns_domain = foo.com.
openstack network set e7b11bae-e7fa-42c8-9739-862b60d5acce --dns-domain foo.com.

# Creating port to verify dns_domain assignment but as you can see in output its using example.com. which is configured in /etc/neutron/neutron.conf file. (question how do i assign dns_domain for each of my network?)

[root@aio1-utility-container-2f1b7f5e ~]# neutron port-create e7b11bae-e7fa-42c8-9739-862b60d5acce --dns_name my-port-bar
neutron CLI is deprecated and will be removed in the future. Use openstack CLI instead.

Hi Satish,

A few question to see if we can reproduce this:

What do you have in you neutron config for...

* 'service_plugins'
* ml2 'extension_drivers'
* 'dns_domain' is set to 'example.com.', right?
* the 'external_dns_driver' and all [designate] section settings also may matter just one step after what you're asking about

Are you going for the following use case? Or another one? Which one in that case?

https://docs.openstack.org/neutron/latest/admin/config-dns-int-ext-serv.html#use-case-3c-the-dns-extension

Did you see these constraints for your network?

https://docs.openstack.org/neutron/latest/admin/config-dns-int-ext-serv.html#config-dns-int-ext-serv-net

Could you please share a 'openstack network show' output for your network?
