There really are such things as Internet simulators, although there are different kinds. I'm in the process of setting one up at Gettlabs, which may not be scalable to a home lab. It consists of multiple routers, plus *NIX PCs running BGP update generators including Zebra and BGPsim.
What this lets me do is to generate more complex AS paths than is possible with a couple of routers in a pod, and also to generate errors (bad AS paths, flapping routes, etc.). The individual user pods see it as several ISPs with various numbers of POPs, with a "reasonable" number of routes -- not a full global table. For a different sort of simulator, look at http://www.ietf.org/html.charters/bmwg-charter.html and you'll see simulator methodology Internet Drafts for BGP and OSPF. You will also find RFCs and Internet Drafts about a different kind of simulator -- throughput testers. Realistically, the CCIE exam does not test Internet routes nearly as complex as we see in the real world. I don't know if there is a market for this more advanced BGP stuff--to some extent, I am doing it as a research project and possibly for custom classes.
