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.

Oh, then why run BGP? It's off by default.
:) very good. I wasn't being deliberately stupid, just pointing out that one might not know that it's on by default. Why do I need a way to autodiscover my routers? I know where they all are-- I put them in after all.
What I'm saying is that CDP is a "negative checkoff" item-- like those little boxes when you download software that say, "check here if you DO NOT wish to receive email when we produce yet another upgrade." If you don't check the box, you will get mail.
If you don't turn CDP off, CDP is on. This is nonobvious to those new to the business.
