There are several of us here who have cisco's doing this, so let us know what your IP is going to be and we can setup some tunnels.
Thank you for the offer. I'll send out a request once I've got the hardware working.

No problem, config is easy. Let me know when you are ready and I'll give you a hand.

I believe your Cisco should be able to do it for you, provided your link to
any other area is directly to the Cisco. It should be able to cope with bridge
connections and GRE tunnels for example. If you have a Multinet link, then I
don't think it can cope with that as that has to terminate on a host system.
A multinet tunnel would need to terminate on a VMS box that is an area router, yes.
I'm not considering using Multinet, so it sounds like I can use the Cisco as the area router. Time for some experimenting.

Hello all,
Question about area routers. I'm going to spend some time over the holiday break bringing some of my machines back online (I'm area 42). My current area router is making some very unsettling hard drive noises, so I'm thinking of retiring it. I recall reading somewhere that VMS Alpha is unable to be an area router - is that correct? I have a DS10L that will probably be my always-on machine.
I also have a Cisco 7206VXR router that can do DECnet. If I use a Cisco for my connectivity, do I need an area router, or does the Cisco fulfill this purpose?

Have a couple questions though about all this.
I'm doing 'NCP TELL foo SHOW KNOWN CIRC' and so my question about that is will all adjacent routers show up on that list?
Also, the output of 'NCP SHOW EXEC CHAR' what are all the possible values for Type?
CHIMPY shows up as 'nonrouting IV' and GORVAX shows up as 'area'. What other possible options are there?

The Network Management architecture spec answers these questions. Quoting from that document (AA-X437A-TK):
"show known circ" will give you all adjacent routers; "show known circ status" will give you all adjacent nodes of any type.
Type can be: routing iii, nonrouting iii, area, routing iv, nonrouting iv. I guess some implementations of NCP use non-standard strings (like "endnode iv"), but the 5 values I listed are the standard strings corresponding to the 5 defined codes in the NICE protocol.
A phase V node would presumably show up as if it were IV, because that's how it presents itself to the Phase IV nodes. You would see what it really is if you ask it directly (but that's a different protocol and a different command syntax entirely).

"Routing IV" for level-1 (non-area) routers.
Ok, so we're up to:
nonrouting IV
Routing IV
area
anyone know of any others?
In RSX is says "Endnode IV", but I assume that is the same as "nonrouting IV".
Also, I'm trying to understand the difference in what info I can gather
here.
Does 'SHOW ADJ NODES' show all known/active circuits as well? Will
'SHOW KNOWN CIRC' ever return nodes that don't show up on the adj node
list?
Different operating systems seems to handle this differently.

Question about area routers. I'm going to spend some time over the holiday
break bringing some of my machines back online (I'm area 42). My current
area router is making some very unsettling hard drive noises, so I'm thinking
of retiring it.
One of mine has been making heart-stopping clunking noises. However, having
backed it up and waited for it to die, it now seems to do it less frequently
and there has been no loss of data, errors logged or anything like that so
far...
I recall reading somewhere that VMS Alpha is unable to be an area router - is
that correct? I have a DS10L that will probably be my always-on machine.
I certainly came across that rumour and rummaging through NETCONFIG.COM on
recent versions of VMS, I see that it has code to avoid offering the choice
of being a router if run on anything other than a VAX.
I can't recall whether I tested this or not but I think that NCP on an Alpha
may be willing to accept DEFINE EXEC TYPE AREA - I suggest giving it a go.
I also have a Cisco 7206VXR router that can do DECnet. If I use a Cisco for
my connectivity, do I need an area router, or does the Cisco fulfill this
purpose?
I believe your Cisco should be able to do it for you, provided your link to

This behaves differently in different operating systems, I've noticed. Just look at the output from MIM compared to some VMS system, for example.
Also, the output of 'NCP SHOW EXEC CHAR' what are all the possible
values for Type?

Good question. I bet there are more than we might know.
Obviously you have three different types for phase IV, but what about phase III or phase V? And I don't know if there might be some other variants.
The ones I have seen are: "Endnode IV" and "Area". But that is when running NCP on RSX. "I assume there is also Routing IV", based on this. I cannot see what phase V nodes looks like, since NCP gives an error when trying to talk to them.
