Read through them. My first reaction is that you are pretty much just letting ACF figure out your hardware, and taking the default answer almost everywhere. That is certainly a valid approach, and it makes life easy. However, if you ever need to start actually change anything, life becomes much more complex, and your guide leaves the user totally helpless. Atleast a few comments about the whats, whys and wheres would probably be useful.
Also, even though you say you have your system installed, finished, and done, it is not. You have not installed RMS, for instance, which many layered produects will require. You built all your tasks to not use any shared libraries, there are potential problems with doing a SAV /WB, as well as the generated system from the VMR step, that you should look at.
Also, there are potentially interesting stuff to change in the SYSVMR.CMD file, before you build your system.
The queue manager is something you start in your SYSTARTUP.CMD, but unless my memory fails me, that is also something that needs some extra steps when you create it the first time, before it actually works in a usable way.
XDT is sometimes a very nice thing to have in your system as well, which you skipped. Might be worth at least mentioning.
I can't remember offhand what else might be good to do/know, but that is partly a problem because I don't use 11M much these days, partly because I know my way around RSX pretty good, and partly because I just forget things. I might remember more later, or after some additional read throughs. :-)
Anyway, it's nice to see someone doing this kind of stuff. Keep at it. Hope someone finds it useful.

Nuts.
Indeed. Anyone have any really good contacts at HP?

Would it cause issues on HECNet having 2 Area 6 routers in different places also? I'm guessing not as they are still on the same DECnet network, same as if they are in the same room on the same LAN, but what do I know ;)
No problems. The only thing is that all area routers needs to have connectivity with other area routers with no level 1 routers in between.
So in your case, your two area routers must be able to talk to each other without using any level 1 routers. However, I don't think that you must have a direct connection between them. I *think* that it should work fine even if they only connect via area routers in other areas.

That's fine, and feasible, and in fact highly recommended if you want to build a robust network.
The one thing to keep in mind is that you need to make sure the area is not partitioned. In other words, if you build for fault tolerance, first concentrate on protecting the area from partitioning. Having done that, build redundancy into the level 2 network.
If you have two L2 routers out of the area, and that area is partitioned, traffic inbound will land on whichever area router is on the shortest path from the source. Area routing (L2 routing) is not aware of the details of what's inside areas; it only pays attention to the area part of the address. So there's a 50/50 chance that the router where the packet arrives into the destination area is the one that can't reach the destination.
BTW, this is a direct analogy with the IP requirement that you have to protect against partitioned subnets, and for the same reason.
I'm not sure from your description, but if what you're trying to do is to have two clumps of nodes that both call themselves area 6, but they aren't connected by L1 routers, the answer is that doesn't work anymore than two clumps of IP hosts that aren't connected but still claim to be in the same subnet will work. Don't do that.

Phase IV network?
Yes.
Restriction, you need are-routers to talk to all area-routers in your
area thorug area-routers..
So you can not have non-area routers as transit between area routers.
If you have two area routers on the same LAN, router priority and/or
node-number will be used by the non-area routers to select wich one
they hand their outgoing traffic to.

I have 4 area routers in area 59, US-east-coast, US-west-coast and two
in Sweden, works fine.

FYI - I m updating Multinet and making a few other changes on LEGATO this morning. It shouldn t require any changes on anybody else s end, but you will see the machine being rebooted several times this morning.

By the way, I assume this means all previous definitions in area 51 are invalid, and were deleted. Let me know if I was wrong. The old ones you had conflicted with this list.

Noted.
I was looking through the archives, I thought I saw that someone had
layered products for ia64 on their machine. Can anyone remind me who
it was ?
I know someone did have something up, but the memory fails me too at the moment.
