Cisco Router Basic Configuration
There are three mode in a router
1. Exe mode
2. Privilege mode
3. Configuration mode
Exe Mode: Exe mode can be determined by seeing that the router in the following symbol:
“router > ” [indicating that router in exe mode],
Privilege Mode: By typing enable [router > enable / en] in the exe mode we can enter in to the privilege mode.

router # [indicating privilege mode]
Privilege mode commands are given below:
# show / sh version
# show history
