so in the host description of e.g. the firewall(s), which are reachable 
through a redundant switchpair, I'd write this:

define host {
        host_name       switch1
}

define host {
        host_name       switch2
}

define host {
        host_name       fw1
        parents         switch1,switch2
}

define host {
        host_name       fw2
        parents         switch1,switch2
}

define host {
        host_name       isp_gw
        parents         fw1,fw2
}

And if switch1 goes  off-line, the reachability logic will still test 
fw1/fw2 as available and ok until switch2 goes away?
Similarly for isp_gw and fw1/fw2?

Nice!
