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

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.

Establish a Console Session
• All Cisco routers include an EIA/TIA-232 asynchronous serial console port. The console port is an RJ-45.
• Use an RJ-45 to RJ45 rollover cable with a female RJ-45 to DB-9 adapter to connect a PC to the console port
