| Overview

As stated in the previous module, there are two types of router-based VPN networks. They are remote access and site-to-site. This module will focus on the Remote Access VPN. Remote access is targeted to mobile users and home telecommuters. The module will discuss the tunneling technologies and protocols that are necessary to secure any type of Remote Access VPN.

After discussing the basics of Remote Access VPNs, the module will discuss how these types of networks are implemented. One of the simplest ways to enable a remote access VPN is to use the two components of Cisco Easy VPN, which are the Cisco Easy VPN Server and Cisco Easy VPN Remote. Both components work together to provide safe, reliable, and secure Remote Access VPNs for users. The module will discuss how Easy VPN works and how users and administrators can use it to ease the creation of secure VPNs. Each aspect of the Web-based Easy VPN client is discussed.

Finally, the enterprise management of VPNs will be discussed. Management is one of the greatest challenges in the implementation of large scale site-to-site and remote access VPNs. The primary role of the Management Center for VPN Routers (Router MC) is to manage Site-to-Site VPNs. The key topics necessary to understand VPNs will be explored. A firm understanding of how Router MC operates will help to better manage large scale VPNs.

NOTE: It is required that the student study the commands covered in the chapter using the labs and the command reference. Not all required commands are covered in sufficient detail in the text alone. Successful completion of this course requires a thorough knowledge of command syntax and application.
