[OT] network monitoring/visibility appliance

I apologize for the off-topic post, but I'm at my wits end trying to "rediscover" a peice of equipment I came across a few months ago but some how lost the datasheet/bookmark too. The appliance was a standard 1U rackmount "pizzabox" that spoke a whole variety of protocols (IS-IS, BGP, OSPF, MPLS + TE, etc). Basically, the pitch was you plugged the box into your network, and it spat out a pretty map with all sorts of interesting information without having to poll (much). I realize there might be more than a few of these products, but I've somehow managed to avoid all of them in my search. Please contact me offlist if you might be familiar with a/the device described above. Thanks Regards, aaron.glenn
