This will only work if the check_command knows how to deal with two ip
addresses. In the current plugins release, check-host-alive (aka
check_ping) does not.

I typically put a loopback IP on the router and monitor that as the host
IP and then have additional IP's on the router defined as services to
that router. It seems to me to be a more granular way of checking the
state of the router. If any of the circuits are up I can get to the
loopback but I can also tell if any of the individual interfaces go
down.
