I have no idea what Cisco equipment Elmar is using, but I wouldn't jump to the conclusion that it can't withdraw routes when needed.
Wouldn't the dns bit of ip sla do most of what's needed on IOS ? http://www.cisco.com/en/US/docs/ios/12_4/ip_sla/configuration/guide/hsdns.html some interesting examples at www.cisco.com/web/CA/events/pdfs/CNSF2011-Automations_for_Monitoring_and_Troubleshooting_your_Cisco_IOS_Network-Dan_Jerome.pdf (slide 29 and onwards) Note: this is more of a question than an assertion, I've used quagga/ospfd for DNS anycasting within ISPs, and a script to monitor the nameserver response, but I'd love to hear what people are doing that's not host based.
