Implementing Cisco Vpns

When it comes to communicating over the Internet, it is critical that the networking technology you're working with is reliable, secure, and will perform smoothly. This step-by-step implementation guide will show you exactly how to implement Cisco-based VPNs effectively. Beginning with an overview of VPN basics--including encryption and authentication--the book covers IPSec, L2TP and other tunneling protocols. Also covered is configuring Windows native support for VPN technology. This hands-on book offers complete and detailed information for understanding and implementing Cisco-based VPN technology. Each chapter is organized in the same easy-to-follow format: a technology overview, IOS version specific commands, and finally multiple case studies outlining effective use of this technology.

With this practical guide you'll be able to:

• Get an overview of dialup protocols
• Configure native Windows support for both voluntary and compulsory VPNs
• Configure GRE, CET, IPSec, PPTP and L2TP using Cisco routers
• Configure IPSec and PPTP on Cisco PIX Firewalls
• Troubleshoot VPN configurations
• Learn from the detailed analysis provided within the multiple case studies within each chapter

No other book gives you both practical techniques and in-depth Cisco-specific information. Whether you need to learn about VPNs in preparation for the difficult CCIE exam or if you want to implement a secure virtual private network using Cisco technology, then this is the only book you need.

This hands-on implementation guide will show you how to implement Cisco-based virtual private networks step-by-step. It not only provides a detailed overview of the various VPN technologies available, it also compares them and discusses how each technology works.
