At my previous job our largest network (we ran something like 8 seperate ones as I recall) was around 500 managed devices, including switches (bay) and routers (cisco/promina). All that was done with OVW, and some plugins we got 'for free' (ciscoworks, bay's crazy OVW plugin for switch management). At networks larger than 500 mostly things are handbuilt and nongraphical... atleast on the one I have experience with. I suppose you can think of it like this: Do you need the graphical info, or do you just want alarms/alerts when problems arise? If you maintain the data in some sane format (think database) you can corellate that info as you want, and generate graphical displays for things of interest. MRTG/RRDTool or RTG are nice packages for somethings, but you might have to have a farm of pollers/graphers/displayers (and a few folks to care for them/create displays that matter) to poll 100,000 interfaces, eh?
