thanks everyone for all responses with the great inputs ..

now if I want to put the DNS servers behind LBs, 1) would the LTMs be able to announce the routes dynamically for the DNS servers, and a VIP can be withdrawn when the site is gone? 2) would the LTMs be able to detect a DNS service failure and stop sending over DNS queries, i.e., in the case a named is still up but just not able to resolve names (assuming LTM can detect a named is down)?
