Well, it makes you wonder why Cisco changed it so that IP routing is now
turned off by default. It used to be on by default, or at least when up
put an ip address on an interface. What really kills me, is that if you
buy a small router, say a 2501 that is only licensed for IP, it comes with
CDP on, and IP off by default.
