I assume its like creating a sub-interface(i think that's what its 
called) on a cisco router. I have limited experience with cisco stuff, 
maybe someone will chime in and fill in the blanks. Anyway its not hard 
to actually do it on a "real" router, just a handful of terminal 
commands is all it takes. Now if I could just remember them all, the 
command completion on a cisco router is pretty effective though.
