Children zones inherit all options of their parents. Attributes
|
|
|
|
defined in a child will overwrite the ones of its parent. Only
|
|
|
|
leaf zones will be actually served. This way it's possible to
|
|
|
|
define maybe zones which share most attributes without
|
|
|
|
duplicating everything. This mechanism replaces nsd's patterns
|
|
|
|
in a save and functional way.

Define your zones here. Zones can cascade other zones and therefore
|
|
|
|
inherit settings from parent zones. Look at the definition of
|
|
|
|
children to learn about inheritance and child zones.
|
|
|
|
The given example will define 3 zones (example.(com|org|net).). Both
|
|
|
|
example.com. and example.org. inherit their configuration from
|
|
|
|
serverGroup1.
