Thanks Mr Luke Lehman for your response . I will just explain my setup . We have Two DC and each DC hosting pair of LTM & Standalone GTM .

 

When User Request say it hits DNS ( Which is Hosted Somewhere in Cloud say GO Daddy ) which then delegates the NS service to GTM by using the subdomain .Once request reaches the GTM it searches for Available LTM VIP .

 

We are using SNI for the VIP .

Thanks for your Answer .

 

Current traffic flow : DNS Request for

 

DNS Response from Public DNS to delegate the request GTM ( NS )

 

GTM Selects the available LTM IP and send the request back to User

 

User sends request to LTM directly and then normal LTM flow starts .

 

What approach we need to put if we are integrated with Silverline . If we can directly configure LTM IP in silver line then we no more require GTM . Kindly confirm as we are delegating DNS query to GTM at the moment.

 

Can you share the call flow that will be very valuable
