of course. you'll need to restart the primary's named after you add the
necessary config changes, of course.. see below.

what you want is to allow transfers from the main dns. so, in the zone config
for the domain you'll want something like:
zone "mydomain" in {
type master;
file "mydomain";
allow-transfer { <address of secondary goes here> };
};
then on the secondary, you need to set it up something like:
zone "mydomain" {
type slave;
file "mydomain";
masters{ <address of primary goes here> };
};
restart the primary's named first so it know to allow transfers to that
secondary. then restart the secondary's named...
btw, O'Reilly makes a really good book on DNS and BIND
