“Typically, adding a secondary DNS server to a zone involves three steps:
On the primary DNS server, add the prospective secondary DNS server to the list of name servers that are authoritative for the zone.
On the primary DNS server, verify that the transfer settings for the zone permit the zone to be transferred to the prospective secondary DNS server.
On the prospective secondary DNS server, add the zone as a secondary zone.”
