> The "depends" tag and the "route" tag are described in the man page for bb-hosts. I use the following:
> route:whq-router1,sdc-router-hsrp,sdv-firewall-1
>
> whq-router-1 is my local router, sdc-router-hsrp is the site router, and sdv-firewall-1 is an internall firewall/router. If connectivity to any of these fails, every test for all systems with this tag will report 'clear' except connectivity -- which will be yellow.
