  1. CCNA 2 v3.1 Module 1 WANs and Routers

  2. Introduction to WANs • A WAN is a data communications network that spans a large geographic area such as a state, province, or country.

  3. WAN Devices

  4. WAN Services

  5. Data Link Encapsulations

  6. Internal Configuration Components

  7. Routers Connected by WAN Technologies

  8. Path Determination

  9. Internetwork Routers • Any internetwork must include the following: • Consistent end-to-end addressing • Addresses that represent network topologies • Best path selection • Dynamic or static routing • Switching

  10. 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.

  11. Router Internal Components

  16. Computer or Terminal Console Connection

  17. Modem Connection to Console or Auxiliary Port

  18. Console Port Connections • Configure terminal emulation software on the PC for the following: • The appropriate com port • 9600 baud • 8 data bits • No parity • 1 stop bit • 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.
