Zone with DNAME has no NS records

[Dev Op]

Hi all!

I have a zone, say it's "mynet.local":

$TTL 3h      ; 3 hours

$ORIGIN pluto.local.
@       IN      SOA dns1 hostmaster.pluto.local. (
    2020061901       ; serial
    1h      ; refresh
    30m     ; retry
    7d      ; expiration
    1h )    ; minimum

    NS      dns1
    NS      dns2

dns1  A  192.168.1.1
dns2  A  192.168.1.2
host1  A  192.168.1.3
...

It's a big zone. Now I want to have a DNAME for that zone to make it shorten.
Say, I want every host in the local domain to be an alias of the same
host in pluto.local domain. If I want to resolve hostname host1.local
DNS server must give me an IP address of host1.pluto.local.
How to do it?

I tried make a zone:
$TTL 3h      ; 3 hours

$ORIGIN local.
@       IN      SOA ns.local. root.localhost. (
    2020061901       ; serial
    1h      ; refresh
    30m     ; retry
    7d      ; expiration
    1h )    ; minimum

@               DNAME   8m.local.

But when I start bind, I got error:

Jun 19 09:13:38 dns1.local bash[28971]: zone local/IN: has no NS records
Jun 19 09:13:38 dns1.local bash[28971]: zone local/IN: not loaded due to errors.
Jun 19 09:13:38 dns1.local bash[28971]: internal-view/local/IN: bad zone

# named-checkzone local ./local.zone
zone local/IN: has no NS records
zone local/IN: not loaded due to errors.

If I add NS servers to local zone I got this error:

# named-checkzone local ./local.zone
zone local/IN: NS 'dns1.local' is below a DNAME 'local' (illegal)
zone local/IN: NS 'dns2.local' is below a DNAME 'local' (illegal)
zone local/IN: not loaded due to errors.

I don't know how to solve this task. :( Help me.
