have you considering pinging the device? Is there some specific process
that you want to poll, or just maintain IP connectivity?
The simplest, most direct, and most accurate tactic seems to me to be
snooping on the routing traffic that the box sends. Since the box
was described as a "Router," why not set up a BGP session to it or
snoop on its RIP, IGRP, or OSPF traffic? If it is more than one hop
away so that its RIP etc. broadcasts or multicasts won't be heard,
why not configure it to unicast them to the monitoring box?
The software to listen to the routing traffic could be any of the
open source, freely distributable implementations of the relevant
protocol(s) on a UNIX-like system. (Well, that might be a problem
for IGRP; so don't use IGRP.)
