[HECnet] Cisco 2501 Routers that can do DECnet area routing and Tunnel over IP Free

I have some 2501 routers, loaded with a "special" version of SW. They have 1 ethernet port, two serial and console and AUX (can do slip/ppp) ports. I'm naove - if they have only one Ethernet port, would that be for the local network side? What would you do then for the Internet, "upstream" side? You put your DECnet native spekaing nodes on the same thernet segment that you someohow can send packets to the outside world from, where you plug your single router ethernet. decnet routing 59.56 decnet node-type area ! interface Ethernet0 ip address 192.108.200.213 255.255.255.248 no ip directed-broadcast logging event subif-link-status decnet cost 15 ! interface Tunnel3000 no ip address logging event subif-link-status decnet cost 15 tunnel source 192.108.200.213 tunnel destination 199.0.131.2 ! I'll give them away to people who can be gateways to the 'Ethernet bridge" part of HECnet.... Will these talk to anything else (for DECnet bridging purposes, that is) other than another Cisco router? They talk to any DECnet thing on the ethernet native, it can be a area router and it talks DECnet in IP/GRE tunnel to another cisco box. P.S. Are you going to be in town for DCL this Saturday? No, I'm getting back to the valley on Tuesday. Now, I plan to do the September DCL. -Peter
