I know that part, I meant to check in Multinet to see where my tunnel was connecting to at Steve's end :)

You know, I was thinking about this. I don't think you should need to do the bridge-group if all you want to do is DECnet routing.
Let's try it without. :-D

Definitely LAT, but I kinda think not for MOP. I mean, everyone has a copy of PR0801ENG.SYS, right? ;)

Sometimes the simplest approach is best. =) Offhand I don't see why that wouldn't work.

Dave,
This end uses the Multinet Tunnel. It also happens to be connected via the bridge. You can install Multinet at the same time that TCP/IP is but you may run only one of the stacks at a time. This end uses static IP addresses but it will accommodate Dynamic DNS addresses at the other end (for Multinet only). All I need is you IP address. This end is 69.21.253.230. Multinet uses port 700 so be sure to forward as necessary.
Regards,
-Steve

Thank you! I'm told that Steve Davidson runs the big hub

Right, as the area/node are encoded in the MAC address. I'm pretty sure the MAC addresses will pop out unchanged.
Oh, and you probably need to pass through both 0x6003 and 0x6004.
Oh ok, thanks for the tip!

Ah, and rereading the stuff right now reminds me of why I never got

Even reading the Wikipedia article, it says:
"A GRE tunnel is used when IP packets need to be sent from one network
to another, without being parsed or treated like IP packets by any
intervening routers."
So, it is essentially for IP traffic. It don't seem to be generic enough
for any random ethernet traffic.
Then, of course, you can run any kind of traffic on top of that IP layer
in the GRE tunnel, and it will all be invisible to the outside. But that
don't help when there is no IP to start with...
No, GRE isn't just for IP. You can bridge most any protocol with GRE. I've bridged non-IP-based Windows networks (for a customer) many years ago using GRE over a WAN. The Wikipedia article is poorly worded.
I'll happily go on talking with people interested in this more, but we
might do it outside of this list, since it will quickly become pretty
narrow and technical.
Ok.

It's not ignorance if you've had no reason to know about it. :-) Generic

Bah!!
I looked at GRE several years ago, but could not make head or tails of
it for the requrements of DECnet, so I gave up on that.
Ok. I'm pretty sure Brian told me that some of the HECnet areas were
connected via GRE, but I (or he) may be mistaken. Either way, I know
Brian spent some time on it a few weeks ago but was looking for
someone to run some tests with. He seems to have disappeared (he does
that from time to time ;)) but when he comes up for air I can work on
that with him. If we can get it working, we'll share configs etc in
case anyone else needs that info.
No one uses GRE that I'm aware of. *I* am interested in it, however. :-D
I could swear you said some people were using GRE..
Tomorrow is the last day at the current client (Nexus 1000v, SRM and
View!) who is annoyingly 3 hours from my house which has been making for
some long, long days. I'll have extra time coming up soon.
I'm glad that one is drawing to a close! Let me know when you're able to try some tunneling tests. My 7206VXR is in the rack and permanently up now, but with no production traffic on it yet. I'm hoping to move all the NAT and other stuff over to it soon, but I can do all the hacking I want on it for now, and reloads won't matter. ;)
I'll type up some thoughts in a separate email.

The bridge program that I wrote does something more or less equivalent.
Most of HECnet is either using the bridge, or else DECnet over IP on VMS
running Multinet.
Ok. I could install Multinet on my DS10L, but I'm already running the DEC IP stack on there...not sure if I can remove that and then install Multinet, or if I'd have to reload the machine. (which would be fine, it's a relatively recent install and I don't have much on there yet)
I don't know the physical location of Steve Davidson, but I bet he can
tell, and help you get connected...
Sounds good, I'll wait for him to pipe up. Thanks!
