Probe dns service - anycast network

Hi,
We are thinking of deploying anycast in our network for dns servers.
I have the following scenario: 
 - 10 server DNS (isc-bind) , linux and zebra for propagating ospf ip anycast.

Are there someone who has developed a "solid scripts (perl/c/ecc..)"
that is used to probe a dns service (udp/tcp port 53) and in case of
failure (or max lookup query time problem) automatic shutdown ospf
annunce or remove a server from a anycast network?

Best regards
Antony Findanno
