The router has 239 KB used for startup con?¬?guration storage in the NVRAM and 62,720 KB
of ?¬‚ash storage for the Cisco IOS Software image.
Summary of Starting a Cisco Router
The following list summarizes the key points that were discussed in the previous sections:
?– The router startup sequence is similar to the startup sequence of the Catalyst switch.
The router ?¬?rst performs the POST, and then the router ?¬?nds and loads the Cisco IOS
image. Finally, it ?¬?nds and loads the device con?¬?guration ?¬?le.
?– Use the enable command to access the privileged EXEC mode from the user EXEC
mode.
?– After logging in to a Cisco router, the initial startup status of a router can be veri?¬?ed
using the router status commands show version, show running-con?¬?g, and show.
Configuring a Cisco Router
When the hardware installation is complete and the Cisco router has the initial
con?¬?guration, you can begin con?¬?guring the router for a speci?¬?c internetwork. You must be
familiar with the Cisco IOS command-line interface (CLI), its modes, and its operation
before con?¬?guring more advanced features such as IP routing. The following sections
describe how to implement a basic con?¬?guration for a Cisco router.
