[Cialug] Routes? Interfaces?

[Josh More]

And for a non technobabble answer:

Interfaces are like interstate ramps.  Routes are like the maps.  If you
have a car (packet) that needs to get to work, it needs to know the
right ramp (interface).  It looks at the map (route) to figure this out.

Of course, the analogy falls apart when you realize that in this model,
it's the ramps that push the cars along.  A train analogy would track
better, but we'd have to add in some sort of automatic coupling and
decoupling algorithms, and then would only work so long as we ignore
packet fragmentation (which would be unpleasant were you in the train
car at the time).  So I use cars instead.

Can someone explain to me what the difference between a route and an
interface is?  You can have a route with no interface, but can you
have an interface with no route?  What good is one without the other?
