Hi this is my first post ever.
I'm stuck on a very simple task that I have not been able to get it to work.
I have done this in the past with older versions of BIND but it has been quite
a while.
I'm trying to delegate to an external provider's nameserver for a "subdomain"
of mine.
The parent zone file works properly and loads and serves everything as expected.
But will not load and serve my NS record pointing an external provider's DNS.
I can get much more specific as need-be
I am on and up to date version of Debian Server and up to date version of Bind9
named -v
BIND 9.18.28-1~deb12u2-Debian (Extended Support Version) <id:>
This is a generic example of what I am trying to do.
The top two parent NS records load and serve as expected.
As well as the A record of course.
But the delegated NS record at the bottom does not get loaded or served when
queried for it
I am using dig as you may expect to determine this.
I must be totally missing something simple but I am totally stumped on this at
the moment.

Thank you for any pointers..
I have spent about a day searching the web before posting.
Many examples say to do it the way I am doing it.
And I've done it before this way.
Not sure what I am missing.
