Zone file:

; Zone file for de.filo
$TTL 86400
@               IN      SOA     ns1.de.filo. j65.de.filo. (

                86400           ; refresh, seconds
                7200            ; retry, seconds
                3600000         ; expire, seconds
                86400 )         ; minimum, seconds


                IN NS ns1.de.filo.
                IN NS ns2.de.filo.

                IN MX 0 mail.de.filo.

localhost       IN A 127.0.0.1

ns1             IN A 192.168.222.245
ns2             IN A 192.168.222.200

mail            IN A 192.168.222.20
www             IN A 192.168.222.20
ftp             IN A 192.168.222.20

; sub-domains

frankfurt       IN NS ns1.de.filo.
                IN NS ns2.de.filo.
freiburg        IN NS ns1.de.filo.
                IN NS ns2.de.filo.

Of course you will need to create additional zone files for the frankfurt.de.filo and freiburg.de.filo sub-domains.

I do not run authoritative DNS in my lab but IRC the last time I looked NSD
one can literally use the same BIND zone files.
