DNS Clone Pool
Hi Gurus, my concern is about if there is a way with an iRule to ask an URL to a DNS's pool and send the traffic to the first responding DNS
Do you want LTM to dynamically look up the IP address for a hostname to clone traffic to? This isn't possible in a simple way as far as I'm aware. I don't think you can dynamically set the destination IP:port to arbitrary values when using the iRule clone command. You can specify a specific member IP and port using the clone command, but I think the address:port combination must already be defined in the pool.
You could open a case with F5 Support asking them to support using a virtual server as a clone destination. With that functionality you could use RESOLV::lookup and the node command to resolve a hostname to an IP address and then set the destination IP:port to it.
