Implementing Cisco Vpns

Set up, configure, and troubleshoot Cisco-based virtual private networks.

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.
