The status maps does not care about dependencies. It only uses the parent
field.

Assume router arwen and host bilbo. You can only reach bilbo through
arwen. (Or at least your Nagios checks.)

Then you would define:

define hostdependency {
	dependent_host_name	bilbo
	hostname		arwen
	.....

I admit it takes some reading and it is propably even more confusing for
those whose native language is not English.

I would have expected:

define hostdependency {
	hostname		bilbo
	depend_on_hostname	arwen
	....

I do recommend to rewrite this to be less ambigious in v3.
