Audience
This guide is intended for network administrators whose backgrounds vary from having no or little
experience in configuring routers to having a high level of experience. You can use this guide in the
following situations:
• You have configured the software by using the Cisco Router Web Setup tool, and you want to
configure additional advanced software features by using the command-line interface (CLI).
• You want to configure the software using only the CLI.
Note We strongly recommend that network administrators with minimal familiarity with Cisco routers use the
Cisco Router and Security Device Manager (SDM)—a web-based configuration tool that allows you to
configure LAN and WAN interfaces, routing, Network Address Translation (NAT), firewalls, VPNs, and
other features on your router. To obtain the SDM release notes and other SDM documentation, go to
http://www.cisco.com/go/sdm and click the Technical Documentation link.
