iRule to update vip address that DNS entry is resolving to.

Hi Cory, thanks for the response. Would this work if the clients are never directly talking to the GTM? The proposal provided to us wants the clients to resolve the FQDN's with the DNS and then directly connect to the clusters vip or an individual server in the cluster.

In our case the plan is to have the DNS server actually handle address resolution, so we want the global load balance to update the DNS server with whichever clusters IP we want the FQDN to resolve to. It would get updated due a outage in one of the clusters or some sort of a performance metric.
