Yes, sorry, I should have described what I am trying to achieve. 
Basically a few virtual nodes talking DECnet, AppleTalk and 
NetBIOS/NetBEUI protocols (no IP), plugged into some virtual switch or 
router that can setup a GRE tunnel to a real CISCO switch on the other 
end, which also has DECnet and AppleTalk nodes on it.

I came across this just now based on the pointers received so far and 
will research this:

Thanks for the information; keep it coming!
