IP路由
Purpose: This figure introduces students to routing. The router must accomplish the items listed in the figure for routing to occur. Emphasize: Path determination occurs at Layer 3, the network layer. The path determination function enables a router to evaluate the available paths to a destination and to establish the best path. Routing services use network topology information when evaluating network paths. This information can be configured by the network administrator (static routes) or collected through dynamic processes (routing protocols) running in the network. Transition: How do you represent the path to the packet’s destination?
