You are not providing a lot of info so that this open tech community can help you to find the best solution 🙂

 

What I can say is if you add a pool to the DNS listener then anything that does not match the F5 GSLB or Express Zone will go that pool:

Outside of that you can attach an irule to the listener and send the traffic to a specific pool or done depending on what works for you:

HI Nikoolay,

Thanks for your reply. 

My requirement is all the servers are configured to resolve FQDN name from the GTM in our enviornment and there is one site i need when the server sent the request to GTM for that URL it should forward to another GTM server (different location not handling by us)  , So for doing the conditional forward in my GTM what is the configuration need to apply , Kindly advice.

Thanks and Regards,
