question about zone files and authoritative nameservers

In our /etc/named.conf file we currently have this:

zone "h1.atd.gme.com" {         
        type slave;
        file "net-dns.hosts.h1.atd.gme.com.";         
        masters {
                201.101.21.12;
        };               

... so we are getting the h1 zone file on our nameserver (a1)

In our own a1 zone file we have the following:   

h1.atd.gme.com.    IN      NS      n12.h1.atd.gme.com.             
                   IN      NS      n02.h1.atd.gme.com.            
                   IN      NS      a1.atd.gme.com.      

to define authoritative nameservers for h1. 
(note that n12.h1.atd.gmeds.com resolves to 201.101.21.12)

So, we get their zone file from 201.101.21.12. We are 
recognized as an authoritative name server for them and 
we successfully resolve their hostnames for them.

The question, then, is if 201.101.21.12 goes down and it
can't send its zone file ... is their some scheme we can 
have set up to begin using the zone file from n02      
(201.101.21.2)? Should we have a slave/zone file statement
for n02 in our /etc/named.conf file?

Thanks very much!!
