Query on GTM listener IP

Hi, please suggest if it will work or not?

 

we have two datacentre Active and standby and GTM is deployed at both end. now for some of the application we have made two entries in public dns and in LDNS towards Active and standby Datacentre-GTM listener IP so that for all specific fqdn request , F5 GTM will respond with respective host resolution . now if we configure only one Listener ip (i.e. of active datacentre's GTM) in LDNS and in public dns, in case of any unavailability in Active GTM-LTM virtual server or backend member traffic should get redirected to standby datacentre (since both VS are configured with proper health monitoring in GTM-WideIP).

    What do you mean by Active & Standby GTM ? Are all the DNS requets being sent to only the Active GTM ? Have you checked the logs to make sure if this is the case ?

     

    Regarding your statement: now if we configure only one Listener ip (i.e. of active datacentre's GTM) in LDNS and in public dns, in case of any unavailability in Active GTM-LTM virtual server or backend member traffic should get redirected to standby datacentre (since both VS are configured with proper health monitoring in GTM-WideIP). If you are pointing to only 1 GTM and if it fails, there is no alternate option, is there ?
