Comment 2 for bug 1968057

From the designate-edge point of view:

Problem space:

We want to use the upstream neutron doc to understand how to configure dnsmasq to hit a local resolver at an edge site.

In this neutron doc topic:

https://docs.openstack.org/neutron/yoga/admin/config-dns-res.html#case-2a-queries-are-forwarded-to-an-explicitly-configured-set-of-dns-resolvers

...you can create a list of one or more resolvers for dnsmasq to use for tenant networks. (Designate uses unbound in downstream RHOSP.) The problem is, that configuration doesn't have a concept of the AZ or edge site. Therefore, setting one list of resolvers for all of neutron might be a problem for some OSP sites that also use edge deployments.
