I like BGP more as I could transport that /32 with no-export
right away.
Yes, in a simple hub-and-spoke anycast topology, iBGP is simplest. In a
wagon-wheel or mesh topology, having an IGP makes some things simplest,
though you can still use iBGP in that role.

PJH configure a loopback interface on your dns servers and advertise a
PJH route to that loopback address to your connected routers...
We've used this approach for several years. It works very well.

It has been my experience in the deployment of such anycasted dns
server pods that pushing ospf from the dns server hosts introduces
complexity and reduces reliability to the point that other, simpler
solutions become much more attractive.

Hi,
I'm trying to set up a anycast DNS server farm for
customer service. In order to improve availability, we
plan to install those servers in
one LAN which has the similar structure like :
