Use this workbook to rapidly configure IPSec tunnels on Cisco IOS devices

As we discuss in the companion article, "Configuring IPSec VPN on Cisco IOS," site-to-site VPN tunnels offer a cheaper and often faster alternative to frame relay or even MPLS WAN connections. This Excel workbook is designed to make it easy for you to generate an IPSec configuration that you can copy and paste into the Cisco CLI.
