Dynamic Pool members from FQDN and monitoring during TTL.

Hi,

 

 

You can use RESOLV::lookup in an iRule to resolve the hostname to IP address(es). But you can't modify the BIG-IP configuration from an iRule. If you wanted to do this you could use a shell script and write the change to the pool using tmsh. You could run the script from cron or using an external monitor.

 

 

There's a related enhancement request to support name based load balancing using DNS so that TMM would do this for you. You could open a case with F5 Support to add your request to it. If you do, reference BZ353855.
