howto prevent notifications on network outages

[Rene Fertig]

Hi.

If a network with e.g. 10 hosts becomes unreacable because the router to this 
network fails, nagios recognize a netwok outage. I get 1 DOWN notification 
for the router and by and by 10 UNREACHABLE notification for the hosts.

How do I prevent these 10 notifications best? Better by setting up 
host-dependencies (and how) or better by configure the hosts in host.cfg not 
to send unreachable notification (set notification_options to "d,r,f" instead 
of "d,u,r,f").
Am I right with my assumption, that nagios only mark a host as unreachable if 
its parent host is down (I've searched the documentation but didn't find a 
description about that)? If not, the latter way wouldn't work propperly.

And is there a posibility to generate a "network outage" notification?

Bye, Rene
