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.) Vernon Schryver vjs@rhyolite.com
