    Hi Preet_pk ,

    Configuration steps for FQDN type node creation is pretty straight forward as shown in the attached snap. Once it is created you can add this node e.g. abc.com under desired pool. That's it! Here you can also customize internal for the specified node.

    Note- When you keep auto-populate as enabled,  the system queries the DNS server for FQDN information at the interval provided in the node configuration and updates the node and pool member list with the information from A and AAAA type records provided in the DNS response. 

    Hope it helps!

Hi Mayur,

Thanks for the update.

Just want to check one more thing - for fast resolution in F5 for FQDN is it recommended to set TTL to 5 min instead of default 3600sec
