Parents and such are considered from nagios' view, with the monitoring 
process sitting at the very top. Hence, the nagios process quite 
naturally has no parents (i.e. traffic going to it self doesn't have to 
pass any other host).

By using a parent statement in the host object definition. You can also 
specify coordinates in the hostextinfo, but that might be a bit 
troublesome in large networks.

Judging by what you've said it seems that the Bronson router is where 
the Nagios server is connected, so that should be a root (parent-less) 
host (all hosts with no parents are automatically connected to the 
Nagios process), and the Oxford router should probably have the Bronson 
router as its parent (assuming traffic from Nagios passes through the 
Bronson router ONLY on its way to Oxford, and that the Nagios server 
isn't connected directly to both the Bronson and Oxford routers).

Then simply explain to him how the network is built and that parents 
exists not only for the sake of having a nice status map, but also for 
suppressing notifications and enabling the niftyness of network outages.
