Hi, There are two TTL object in GTM. You can change TTL value based on requirement.

  1. You will find TTL object while configuring Pool.(default TTL value 30Sec).

  2. The system uses the value of the Time to Live (TTL) field in the DNS record, and the 

    max-cache-ttl
    statement in the BIND configuration file, to determine the time frame that the records remain in the cache. Link

                DNS-->Zones-->ZoneRunner-->named Configuration.
            example: max-cache-ttl 90;

Hope it will work.

Thank you Samir, In the UI when I login and go to Zones-->ZoneRunner-->named ConfigurationI do not see max-cache-ttl, I just see TTL. Is this in the GUI or I need to SSH into the unit? If i go to DNZ there is no Zones under that menu in version 11.4.1. Thanks.
