That really opens it up. ;) Simh emulates several platforms for which
there are DECnet implementations:
PDP-8: there's a DECnet implementation for OS/8.
PDP-10: TOPS-10, TOPS-20
PDP-11: RSTS/E, RSX-11/M/M+
VAX: VMS, Ultrix
The PDP-8 DECnet is actually for RTS-8, and not OS/8. However, it's also
only PHASE II, so I think we could rule that one out.
Oops! My mistake, thank you for the correction. I thought it was for
OS/8. I consider myself to be a PDP-8 aficionado, but I've never seen
the DECnet implementation
For PDP-11, I think that there was also some kind of DECnet for RT-11.
And you have IAS, as well as (probably) RSX-11D.
I don't think there was a DECnet for RT-11, but I could be wrong.
Isn't IAS basically a chopped-down RSX?
Also, I wonder if VAXELN also had DECnet?
I'd imagine so, but I'm not certain. I'd guess yes because the
firmware for some of DEC's X terminals is based on VAXELN, and early X
implementations supported X over DECnet.
And isn't there some sort of Alpha in simh as well nowadays?
Barely, but yes. It's not really far along enough to be useful yet.

Hello!
Okay think of it this way: What operating systems can be connected,
and running on what (emulated) hardware?
Oh!
Do you also want to know versions of software? That can become a rather
complex list.
Not even sure anyone knows the full answer... There are/were DECnet
implementations for quite a few systems.

Various such lists have been started over time, but I don't think anybody
was willing to maintain them.
I agree that it's hard to figure out routing issues when the network
topology is unknown! A nice HECnet map would be worth its weight in gold
about now.
Area: 2
Name: Bob Armstrong
Location: Milpitas, CA (Western US)
Router: LEGATO:: - connected via bridge and Multinet Tunnels
I have a list which is pretty authoritative on who "owns" each area, but I have not kept any other information around, such as routers, geographical information, or anything similar.
Partly also because areas are not necessarily geographically coherent.

"This signature does not exist!"
Ditto here, although there are fewer nodes/areas online now than
previously. LEGATO continues to think that it can reach areas 52 and 59 via
A54RTR, although I don't believe any nodes are actually up in either area.
As far as I can see, LEGATO is probably correct in what it is thinking.
The GRE tunnels from A54RTR to area 59 are up.
a54rtr>show decnet neighbors
Net Node Interface MAC address Flags
0 59.60 Tunnel590011 0000.0000.0000 A
0 59.59 Tunnel590059 0000.0000.0000 A
0 54.59 Ethernet0 aa00.0400.3bd8 V A
0 54.188 Ethernet0 aa00.0400.bcd8
a54rtr>
Attempting to query some nodes in area 59 results in:
-SYSTEM-F-NOSUCHOBJ, network object is unknown at remote node
which sounds like a node that is reachable but doesn't have an NML listener.
If the node was not reachable the resulting error would likely be:
-SYSTEM-F-UNREACHABLE, remote node is not currently reachable
