How to configure stub zones in Address Manager.
Configuring a stub zone involves the following:
- Create an Other DNS server representing the primary DNS server.
- Create a zone in Address Manager to represent the authoritative zone.
- Assign the Primary deployment role to the external server.
- Assign the Stub deployment role to the DNS/DHCP Server hosting the stub zone.
The DNS server hosting the stub zone contacts the primary name server and updates the zone with SOA, NS, and glue records at regular intervals. In this view, the DNS server hosting the stub zone is kept up-to-date of any changes to the name server and glue records.
When a client queries a stub server, the server sends a recursive query to one of the
authoritative DNS servers listed in the stub zone. The authoritative server responds
to the server hosting the stub zone. The stub server then responds to the
client.
Note: Because stub zones
require recursion, recursion is automatically enabled when you deploy a configuration
with a stub zone.
