Other Rules of the Road

Other Rules of the Road

Although a single example might help you understand routing, one example can't cover every nuance of how routing works. Before wrapping up this chapter, you should be aware of a few additional short topics about routing. These last few topics do not change the rules of routing, but they do clarify what happens in a couple of different instances.

In the example used throughout this chapter, three different IP networks were used, with no subnetting. As it turns out, even with subnetting in use, routing works basically the same way. For example, look at Figure 11-13, which has the same internetwork with two routers, but now with subnets of Class B network 150.1.0.0 in use.
