dns zone delegation

[Gopinath Achari]

Hi,

                i have configured a Master DNS server, i have also created 
records to delegate a zone to child dns server
But when named service is started it says 

Jul 31 14:33:30 localhost named[21581]: dns.zone:9: ignoring out-of-zone data 
(child.dns.com)

I am using bind-9.3.4-10.P1.el5_3.3.  on Centos 5.2
 
Please help. Thanks in advance. 

how to delegate the zone, is there any other configuration needed


my zone file ...

$TTL    86400
@       IN      SOA     dns.com. root.dns.com.  (
                                      1997022700 ; Serial
