Older network designs sometimes made extensive use of routers. To keep broadcast traffic under control routers were sometimes used to create network segments—although bridges were more commonly used for this purpose—and to help distribute traffic load. Newer network designs replace the routers with multilayer switches. [1] A network built around multilayer switching technology allows you to keep your network design more streamlined, and means that you only have a single router, or pair of routers, to worry about.
[1] Multilayer switches are discussed in detail in Chapter 5. They are switches that combine the speed of Layer 2 switching with the intelligence of Layer 3 routing.
