Who is using ExaBGP for their Anycast DNS deployments?

Greetings /r/networking,

I am gathering information for a proposal to deploy ExaBGP 4.0.8 on Debian 10.4 running Unbound 1.9.0 and IPTables to serve about a dozen DNS resolver IPs in an ISP network. I've got it running in a lab peering with ann ASR 9010 with the most basic health check script just to test the announcements and setting MED/Localpref. In production I would probably end up sending the announcements from each cache to our route reflectors but it would be helpful to hear from some folks that have used it in the real world.

Thanks in advance for your time. I really do appreciate anyone who takes the time to tell me about their setup and how it has worked for them.

-Mike
