Question on GTM load balancing

Hi MSK, do you have any topology rules configured for the current set up ? if so you may have to go under option TOPOLOGY and change the rule under that . If not you have to derive couple of topology rules and configure as per your requirement(it can be location specific). Please have a check on the below link for your reference :
