My HECnet routing involves a layer 2 OpenVPN and a simh instance on my VPS... The two Airport devices give me a wireless bridge in to my garage, where the VAXen live. Ian

Well, since you asked. :) Cable modem plugged into Cisco 1841 router. Cisco 1841 router plugged into Cisco 3560g switch. (VLAN trunked) VLAN trunks extend into VMware environment where I run a pair of OpenBSD+pf boxes for redundant firewalls, so logically it's 1841 <-> firewalls <-> switch. Cisco 1811w plugged into 3560g for wifi access. Other than that it's all hosts plugged into the 3560g or connected via wifi. Oh, and OSPF keeps everything sane. -brian

To answer my own question, I found a reference at Cisco for something they call OLD-CISCO-DECNET-MIB ftp://ftp.cisco.com/pub/mibs/v1/OLD-CISCO-DECNET-MIB.my Maybe that's the SNMP answer? Ian

It is also dependant on the class of router. The SOHO 800 series routers (like what I use) won't do DECnet. Tim.

My Cisco is runnning 12.2(40). According to the documentation, anything newer than 9.1 (ANCIENT) supports it. I've got an 1841 running 12.4(25f). It is also reported to also still work in 15. -brian

Hmmm, Just had a thought. There's a Cisco emulator out there (GNS3 is the GUI, but there's command-line stuff that's lower footprint) that emulates Cisco very well - a 7200-series router is supported. All it needs is a ROM image. I wonder if emulation would be powerful enough to pass Decnet traffic? Cisco Decnet routing without a physical Cisco?

Hang tight. Let me know if I can offer any help. I can give you access to my router if required. I just tried an snmpwalk looking for anything slightly DEC-related and I can't find any data that looks like decnet addresses or anything. SNMP would also require public IP connectivity, which isn't strictly required for decnet to work. For example, my Cisco is using a 192.168 address, and I forward GRE packets (for the tunnels) from my firewall. Ian
