Peter! It's great to see you in this gang. It has been a long time;
I hope you're doing well. Drop me a note sometime and let me know
what's been going on over there.
If you and Brian and I set up three tunnels between us, will IOS do
spanning tree between them?

I have a couple of Cisco 2500's. Which IOS version is needed?
c2500-d-l (requires 8MB DRAM) - IP/IPX/AT/DEC feature set
or :
c2500-js-l (requires 16MB DRAM) ENTERPRISE PLUS feature set
both require 16MB Flash.
I can download both of them just as soon as Cisco fixes my CCO account.
AGAIN.
For the 6th or 7th time in 2-3 months.
This is getting rather annoying.
Yes. I happen to have those images; they're up at:
http://www.neurotica.com/misc/ios/
I'll leave them there for a few days.

If you have a cisco router and want to play let me know. If you don't
have the right version of IOS I can get it for you.

What IP address(es) should I point my tunnel(s) at?
My end will be bart.4amlunch.net (216.15.64.181).

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.

GRE doesn't need to specifically support DECnet; it should happily
tunnel anything. All you need to do is set "decnet cost <n>" on your
tunnel interface.
-Dave
GRE tunnels use the ethertype to indicate the protocol being
encapsulated. In the case of DECnet routing on C the tunnel is treated
as Ethernet between two routers. Unfortenly the RFC's are a mess, the
"mobile world" showed up to help..
You can also use l2tpv3 and make a ethernet bridge like Johnny's.
(but, use the router...)
(Xconnect the two ethernet port you want to bridge between..)

The 11.x does have DECnet routing for sure. Even the 9.x had DECnet routing, because the DECbrouter90's came with IOS 9.x and then both DECnet and OSI routing was included. But I'm not sure when GRE was introduced. I have the 9.x manuals for the DECbrouter90's but I'm not sure if DECnet can be tunneled using the tunneling which was in that version. In the manuals there aren't anything mentioned about that.
I have also the 11.x IOS manual. I have to check there if GRE is mentioned with DECnet.
But if someone knows the answer, please tell.

This doesn't require much horsepower; a 2500 should be more than
enough. I don't recall when GRE was introduced in IOS, but it's nowhere
near recent. We'll just have to figure out which 2500 IOS release has
both GRE and DECnet support.

A quick check you could do is:
conf t
decnet ?
If you get a list of sub-commands you should be good to go.
If you don't, email me a list of the exact models of routers, the amount of ram they have and the amount of flash they have and I'll get you the latest images.
He may have a flash and RAM issue; the 2501 tops out at (if memory
serves) 16MB of RAM. I don't recall how much flash they can take
offhand. 2500s run from flash, as opposed to loading the contents into
RAM and executing from there, which is a nice advantage for reducing
memory requirements for a given feature set.
