Hi Johnny!
No stress. I was just overly enthusiastic.

Sorry, Alastair. I've been rather busy, but I did see your mails. I'll
get to it later today, I hope.
Anyway, the config looks ok. If you are available later today/tonight,
we could try get you up and running...

G'day,
I'll send here because I suspect my emails late last week to Mr
Bilquist
may have been consigned to a junk mail folder. I wanted to (please)
apply for a HECnet address initially for one my main VAX at home,
later
the 11's after I get some more time to work on the hardware.
I managed to get the bridge software to compile under IRIX 6.5.29
via
GCC 4.6. MIPSPro refused with a couple of trivial errors. I believe
I
have the config file correctly set up and the ports.
The relevant bits of my conf look like:
!START
[bridge]
local ec0
update tempo.update.uu.se:4711
[decnet]
local
update
[lat]
local
update
!EOF
Port 4711 is forwarded to my system correctly through firewalls. My
external static ip is 202.168.106.176/ns4.reboot.net.au
Suggestions/constructive abuse welcome :)
Regards,
Al.

Should I set the cost differently than what fa0/0.2 has or should they all be the same?

What I haven't found out is when the IP tunnels were introduced in the IOS=
. It seems to be in IOS 11.2. So it is included in all recent
versions, but the Cisco 2500's have limited flash and RAM
capabilites. Therefore the recent IOS's cannot be used with older
hardware. I suppose the IOS 11.2 should be sufficient for tunneling
DECnet over IP.
GRE 9.21s that was renamed 9.20.. I wanted to talk Chaosnet over IP
and we wanted a generic way of doing foo-over-IP. But, before the GRE
code worked Kirk broke Chaosnet, so there is no official release that
does GRE and Chaosnet .._:)

The 2500s can easily run 12.
I have to check which versions I have on my 2500's. Most probably they have an IP-only version of the IOS. I bought the 2500's cheap from a local broker a few years ago.
There are a handful of versions that have DECnet. It's likely you have ip only though but who knows. Either way, we can get you what you need.

So I guess that DECnet is available on anything you have running.

It's definitely a feature set issue. The last time I did anything
with GRE (before this anyway) was between a 2501 and an AGS+; the former
was running IOS 10 and the latter 11. DECnet support in IOS goes back a
good bit before that, which shouldn't be surprising given the history
(and reason for existence) of Cisco.
I don't think getting GRE support should be an issue, I believe that's
included in all versions, you just have to make sure you get the right
version for DECnet.
Cisco has a feature navigator tool on their website. That can be used to figure it out.
I've not tried that yet. That sounds very handy.

The CCIE at work pointed me to that. Very helpful.

Peter! It's great to see you in this gang. It has been a long time;

If you and Brian and I set up three tunnels between us, will IOS do
spanning tree between them?
Spanning_Tree? This is the distater that Jonny started with ethnernet
bridges..... (on the other hand without that there would be no HECNet
so I'll be quiet, I just wish he changed it to do l2tvp3, don't need
to do the signalling just the encap..) (it don't solve the loop
problem, but now a c router could terminate a Jonny tunnel..)
I'm definitely not boasting about the bridge. :-) It is a hack. But it's much better than the first hack I did for HECnet (which was basically transporting a serial stream point-to-point, and setting up DECnet with a asynch serial port doing DDCMP).
I've not heard of l2tvp3 before. Might be worth checking in to. But the biggest issue really is the looping. And I'm too lazy to implement stp... Well, I might get the inspiration one day, but I'm way more interested in writing stuff for RSX.
DECnet-4 has a link-state routing protocol, it's what Radia did before
IS-IS, it has L1 and L2 routing decided by the area number.
Funny you should mention that, as I always thought IS-IS looked rather a lot like the DECnet routing.
So, as long as the tunnels are PTP between routers it will do DECnet
routing, and the metric is cost and hops (look at a ethnernet routing
vector it's indexed with node number and has cost,hop in 16 bits..)
In short, do nothing, set metric to 10 all all over the place and it
will just work.
What is your IP address? Mine are on the HECnet mailinglinst.
Letting the Cisco partiticpate as routers on DECnet is really the best way to go.

No, because they aren't switched ports.
It certainly comes into play when bridging, say when bridging across GRE.
DECnet, however, should do the right thing assuming we get our DECnet
costs setup correctly.
Ahh, that makes sense. DECnet over a WAN is a new thing for me. Fun
stuff!
