STUPI has nothing to do with it and doesn't know about it. Bob's right; these are GRE tunnels (Peter is a hard-core Cisco guru), both to Peter and to Brian H. (who is quite sharp with Cisco stuff as well!) So how can we do this...I don't think IOS implements NICE, but I'm sure its DECnet routing table can be pulled out via SNMP. Brian (Hechinger), I can set up a read-only SNMP community and your poller (when it discovers an appropriate router) can walk the tree, maybe? And either Sampsa's code can parse that output, or you can reformat it into a consistent format to hand to Sampsa? What do you think? (snmpwalk is your friend!) This is being written in python so I'm sure I won't have any trouble accessing SNMP. I hope. :) I have my router as well, but the more data points the better. I'm nowhere near looking into that just yet however. I will keep you all informed. :) -brian

I don't know much about the details of SNMP, I can look it up of course but I guess there would need to be a format for the routing and end node data, if I can match what CISCO produces then that would make it easier, anyone have any info on this? You guys got off into the woods fast. :) I will look into non-dec router devices after we get the dec ones nailed down with my current code. I'm thinking possibly SNMP for the cisco devices, yes. Not 100% sure that'll work though. As to your router if you don't want to bother with NICE or SNMP just let me know how I remotely query your device. How that happens is up to you so long as it isn't silly. :) A simple API that shoots back something like JSON or XML is fine, for example. We'll talk later when I get to you. :) Just to cover something here, as far as non-bridge link I *will not* do manual stuff. That's just icky. For the bridge connections I don't see that we have a lot of choice so we'll have to think on that when we get it. -brian

If the CISCO guys want on the map, it'll have to be manual for now.... You'll have the same problem with Rob's DECnet router... And possibly other equipment, or nodes that don't want to talk NICE. I have just downloaded the spec and will think about how easy it would be to add this to the router, not that anyone other than me uses it :-( Johnny

Getting a virtual cluster connected

by rok.vidmar＠gmail.com

The DECNET.TXT file obviously had incorrect (very old) information for area 42. The same is true for Area 3: Area 3 Patrick Caulfield Chrissie kindly resigned this area to me. -- Regards, Rok
