NimbostratusRight way of configuring GTM and parent DNS?
The training manual has this to say about the steps to migrating to a system where the GTM will only receive requests for wide IPs within a domain.
Configure the existing name databases on t...
Both are actually valid approaches that are widely used. GTM automatically creates the required zone file including the appropriate SOA info when any name is added as a WideIP.
However, F5's recommended best practice is actually the first: To use a CNAME in your primary DNS that points to a name in a subdomain delegated to GTM. That way you are delegating only the name-to-IP relationship, and the parent zone configuration is still authoritative for MX etc.
