GTM persistence with load balancing

We have an enclosed validation environment which forces clients to use the same local DNS. We're running round robin on the GTM, and after turning on persistence all the clients are being sent to onl...

Additionally, I would think without persistence and with round robin your clients would continually flipflop between datacenters all together when the LDNS cache times out, it queries the GTM and potentially receives a different answer than the last one, sending all clients to the new IP until that cache times out again.

We also have similar situation with GTM routing traffic to two LTM (2 Datacenters ). Both LTM & GTM is having round robin algorithm and LTM is enabled with cookie insert persistence. Current problem since GTM is not maintaining persistence and routing the traffic everytime to different server with in same session client application is not working and prompting login on every page.

 

Client application is IBM Call center application for order processing.

 

please let me know is there a way we can maintain GTM persistence and maintain sessions and send the requests to same server for an established session and do load balancing between two data center.
