wild card question

[Farid Hamjavar]

bind 8.1.2

greetings,

Can I remedy issue described below
via usage of wild card? If not, is 
there other way to accomplish this?



Subdomain "xyz.unm.edu" has its dns server. 

At "unm.edu" level , how can I make 
all queries of type   *.abc.unm.edu
to go to dns servers at xyz.unm.edu ?

I guess I can do :

*.abc.unm.edu IN A   <IP of dns-server.xyz.unm.edu>


Is that legal?
Is that correct way of doing it?


Thanks,
Farid
