What this message means is that the nameservers (pointed to by the NS
records) reside within the zone for which they are authoritative. For
the nameserver of the zone above (in this case dom1.ru) to be able to
provide a response including the IP addresses of the nameservers for the
subordinate zone, you need the IP addresses in the parent.
In other words, yes, you should add A records for the nameservers that
live within the zone in question. I'm thinking that your example is
sub1 NS ns1.sub1.dom1.ru.
In this case, you need to add:
ns1.sub1.dom1.ru. IN A x.y.z.a
ns2.sub1.dom1.ru. IN A l.m.n.o
to the dom1.ru zone file. (that's the "glue")
