We did that with our internally anycasted recursors at my former network. A script withdraws the routes if bind isn't answering. Works great. On 5/3/08, Mike Lewinski <mike@rockynet.com> wrote:

Possibly a good argument for allowing the DNS servers to originate the routes for them...? I've seen configuration where the routes were injected based on link state via crossover cable, so at least if the whole machine pukes the route is dropped. But if the resolver or OS itself is just hung then yeah...
