DRP design help

Hi

 

i am desiging now a DRP solution using 2 GTM's ( in cluster )

 

and 2 LTM's ( also in cluster )

 

i have 2 sites connecting with L3 connectivity ( provides by local ISP ) { no layer 2 for now ).

 

the gtm monitors the ltm thats monitor farm status , when one VS on the ltms goes down the GTM will forward DNS queries to other site .

 

pls tell if its ok , and what do you think ? how can i improve it ?

 

and how will i force DNS quries to go to actvie Gtm machine ?

 

 

have a look { pls } on the design (png ) attachment.

 

Roi.
