Oh, I thought this was an external-versus-internal scenario. But, this
is even easier.
A) One of the nameservers (pick DNS1 or DNS2) becomes a slave (of the
"stealth" variety, if you want) of the other
B) People use nsupdate to maintain the zone
For security, TSIG-sign the updates. For fast change propagation, set up
NOTIFY if and as necessary.

Dear John, this is my scenario:
1) Office 1: people work with some machines and fill up a local master
zone "company.com <http://company.com>" with records in DNS1
2) Office 2: people works with some others machines and fill up a
local master zone "company.com <http://company.com>" with another
records in DNS2
So both office have a different master zone.
Both offices belong to the same company, so I need that any client PC
can resolve a hostname from "company.com <http://company.com>"
domain, independently if this record is in DNS1 or DNS2.
Thanks again, regards.

Hi Jeronimo,
First of all, please just tell us the real domain. Yes, we could
try and talk about a fictitious "example.com <http://example.com>"
or "company.com <http://company.com>," but having the real domain
name lets us actually query your nameservers.
Let me be sure I understand: you have two DNS servers. Each of
them is authoritative for the same domain. Are both set as master?
The two servers have different copies of the zone--what's your
reason for that?
If both servers think they are authoritative for a zone, then they
will answer recursive queries for those zones themselves. From
the manual:
"Forwarding occurs only on those queries for which the server is
not authoritative and does not have the answer in its cache."
What exactly are you trying to achieve?

Dear, I would like to ask for solution related with DNS (bind)
configuration to allow forward requests to another DNS but
related with the same domain.
I'm asking about two authoritative name servers serving the
same domain but with different zone file info on each and have
one of them forward recursive queries to another one if first
one cannot find some particular subdomain record that is
missing in his version of zone file.
My named.conf.local is as follow, but it doesn't work:
zone "company.com <http://company.com>" {
type master;
file "/etc/bind/zones/company.com.db";
allow-transfer { key "company"; };
check-names ignore;
forward first;
forwarders { 172.16.1.1; };
};
Thanks a lot,
JeLo
