Mohamed,

 

I'm attemoptign to setup on the GTM's. I tried global availabiliy and Topology settings. Seems that it is doing round robin only. I see Europe connectons in the US DC's and US in Europe.

LDNS just means local DNS server, and so in GTM context, that simply means the client. If the client IP is in the US, use US data center....etc. Now, you are right, the fact that your European DC does not have GTM makes it sound a bit odd... but should not really be a problem I think. Do you have LTM in Europe? How is GTM configured? one wide_ip? and how many pools? what's in each pool? three data center objects?.... Some combination of all these confguration objects should provide what you need...
