None of us are doing this because it's a mission-critical network (for some of us, that's probably what our day jobs are anyway) - we're doing it because it's fun, and we can play with 'what-if' without breaking anything important. Sometimes the tone in here gets a little serious. Well yes, but that's not necessarily a bad thing. Many (most?) of us here are professionals. There's nothing at all wrong with "doing it right". If it's worth doing, it's worth doing right. I'd just like to say Thank You to everyone on the network for giving us all this huge plaything that we all dreamed of playing with a quarter of a century ago :) Seconded! -Dave -- Dave McGuire, AK4HZ New Kensington, PA

But emulation is free and here today, instead of waiting two weeks for an Ebay order to arrive :) Maybe I should try playing with it to see if it's even possible. If we could create a nice simple turnkey VM image, maybe more Hecnet members would implement it... When you put it that way...hmm that's a nice idea. Let me know if you need any IOS images...I have, umm, pretty much all of 'em. Yup. I need some please. :p -Dave -- Dave McGuire, AK4HZ New Kensington, PA

Also, the metrics are set on the circuit, and not individual destinations. While this worked more or less ok for DEC back in the day, with the bridge, the cost of two different destinations over the same circuit could in reality be very different. Bridged ethernet is a BAD thing for most protocols. And if you use spanning tree, it's not making optimal use of the topology. Radia finally came around and "Trill" is a routed network to carry ethernet frames. As the cost/hop is in the routing vectors being sent periodiacally, you could implement a "cost/hop" NAT (half nat, one half on send one half on receive and some protocol to exchange how you want the metric matrix to look). -P

Perhaps I could learn using dynamips, it'd be easier than re-learning all of Vyatta. If you want to learn Cisco, GNS3 is the cheapest way to go. There's tons of youtube videos showing different Cisco scenarios using GNS3. Ooooh. It looks interesting. Now I just need to find an IOS image. ;) Ian

If one needs to route, one should, oh you know, use a router. ;) I could install vyatta which is linux-based meaning I could /maybe/ build linux-decnet and have it function as an area router. Management could also be done via SNMP, but not to the ease of Cisco. Thoughts? Get a Cisco. It's not like they're tough to find, or very expensive. And you'll use it essentially forever.
