As far as definitions are concerned, I'd have to agree with Anthony on
this. A router routes layer 3. Some routers do more and are better at
certain things, but its basic function is to route layer 3 traffic.
On a related note, in my home lab I have 25xx's and Olives (PC with
JunOS, based on a unix kernel). I can easily bring the 25xx's to its
knees while not even breaking a sweat on the Olives. I heard rumors
that Olives are equivalent to 4700's, but I have not confirmed that in
testing.
