  2. Objectives • WANs • Routers

  3. WAN

  4. Introduction to WANs • A wide-area network (WAN) is a data communications network spanning a large geographic area such as a state, province, or country.

  5. WAN Devices

  6. WAN Services

  7. Data Link Encapsulations

  9. Internal Configuration Components

  10. Routers Connected by WAN Technologies

  11. Network Layer Path Determination

  12. Academy Approach to Labs • In the academy lab, all the networks will be connected with serial or Ethernet cables and the students can see and physically touch all the equipment. • Devices that make up the WAN cloud are simulated by the connection between the back-to-back DTE-DCE cables.

  13. Router Internal Components

  14. Router Internal Components

  18. Computer or Terminal Console Connection

  19. Modem Connection to Console or Auxiliary Port

  20. Connecting Console Interfaces • Configure terminal emulation software on the PC for the following: • The appropriate com port • 9600 baud • 8 data bits • 1 stop bit • No parity • No flow control • Connect a rollover cable to the router console port (RJ-45 connector). • Connect the other end of the rollover cable to the RJ-45 to DB-9 adapter • Attach the female DB-9 adapter to a PC.

  21. Connecting LAN Interfaces

  22. Router Serial WAN Connectors

  23. DCE Serial Connections
