Purpose: This graphic illustrates a multipoint subinterface example. Emphasize: In this example, the subinterface is configured to behave as a normal NBMA Frame Relay interface. No IP address is configured on the physical interface. It is important that the physical interface NOT have an address, otherwise routing will not work. The frame-relay map command is used to create the multiple PVC connections from a single interface. All connections are in the same subnet. The DLCIs are provided by your service provider. Purpose: Review the summary items with your students. Emphasize: Read or restate the summary statements. By now, your presentation and classroom discussion should have students able to meet the chapter learning objectives. Purpose: Review the chapter with open ended questions. Note: The questions in this section are open ended questions designed to foster further discussion. Answers the the review questions are in the “Answers” appendix.
