For our Anycast DNS, we actually use OSPF (Quagga) on FreeBSD, upstream
those to a router, and then redistribute them into IS-IS (since that's
what we run for our core).

Personally, I find the use of an IGP for this kind of thing easier than
BGP, as those IGP routes are all internal, and are covered by the BGP
aggregate we send out to the world.

Of course, unlike Joel and the rest, I don't run a large farm of
servers, so I may not be immediately seeing the value of going with BGP.
