Default Configuration
When you first boot up your Cisco router, some basic configuration has already been performed. All of
the LAN and WAN interfaces have been created, console and vty ports are configured, and the inside
interface for Network Address Translation (NAT) has been assigned. Use the show
running-config
command to view the initial configuration, as shown in the following example for a Cisco 819 ISR:
