Classless in-addr.arpa delegation problem

[José M. Fandiño]

hello,

I'm trying to make work in a test network the Classless 
in-addr.arpa. delegation. Following the 2317 
example I created the zone.

named.conf:
zone "1.168.192.in-addr.arpa" {
        type master;
        file "db.192.168.1";
}; 

---

db.192.168.1:
$ORIGIN 1.168.192.in-addr.arpa.
@       IN       SOA    wintermute.internal.
postmaster.wintermute.internal. (
                                        2000082302
                                        10800
                                        3600
                                        604800
                                        86400)

0/25            IN      NS      wintermute.internal.

$GENERATE 1-127 $ CNAME $.0/25  

---

and after of reload the ns I get:
24-Aug-2000 17:17:13.175 Zone "1.168.192.in-addr.arpa" (file
db.192.168.1): No default TTL set using SOA minimum instead
24-Aug-2000 17:17:13.175 Zone "1.168.192.in-addr.arpa" (file
db.192.168.1): no NS RRs found at zone top
24-Aug-2000 17:17:13.175 master zone "1.168.192.in-addr.arpa" (IN)
rejected due to errors (serial 2000082302) 

any idea?

thanks,
