Sub-domain delegation for BIND 9.2.3

[Apache Apache]

The setup that I have is on an Intranet enviroment. I have setup another DNS 
(ie. for testing purpose) on BIND 9.2.3, configure the Pri DNS for 
company.abc.com to delegate xyz.company.abc.com to this test server, added 
"forwarders { };" to named.conf of the Pri DNS and able to perform the 
nslookup for host.xyz.company.abc.com. However when I change the delegation 
to the F5 DNS, I got the error message SERVFAIL when performing nslookup for 
host.xyz.company.abc.com.

Kindly advise what could have gone wrong.

Beside different DNS program (ie. both the PRI DNS and test delegation 
server running BIND 9.2.3 and the actual delegation server for 
xyz.company.abc.com on F5), the other difference is the ip address of the 
servers. The PRI DNS has IP 130.1.2.3, the test delegation server has IP 
130.4.5.6 and the F5 DNS has IP 172.7.8.9. Would this pose any problem???
