Limiting alerts when remote network is down

[MurrayL]

I'm after some method(s) to limit alerts from systems that become unreachable due to a network link failure. I'd like to see just one alert for the link but not multiple alerts for the systems sitting behind that link (that have not actually failed). I'm looking at doing this via Actions but not sure this is the best method. Thanks in advance.

Thanks for your reply Kloczek,
I should have mentioned, I have looked at using trigger dependencies but thought this might amount to a lot of work editing for each host (?) unless I'm misunderstanding the process. I was focusing on doing it via Actions but couldn't seem to get the logic right or perhaps it's just not possible that way, although what I did do was add a custom script on the Zabbix server via the Action Operation which runs a ping against the router then checks the error level of the command so if it is a positive result, ie router is pingable and the server behind that router has a problem then it will tell me (via some more scripting yet to be worked out) , or if the router is not pingable then end the script and don't tell me if the server is unreachable. Thoughts ?

Use a template that has the trigger with the dependency, and attach it to the hosts.
