GRE tunnels are commonly used to send multicasts through a network (such
as the Internet) that cannot route multicast messages. For example, routing
protocols such as RIP v2 and OSPF send multicast updates. A tunnel can
encapsulate the updates and carry them through the network that does not
support multicasts.
See Chapter 9: Configuring a Tunnel with Generic Routing Encapsulation
to learn how to configure a VPN overlay with such tunnels.
Physical Setup
You must purchase a 7100/7200 IPSec VPN module in order for your ProCurve
Secure Router to support a VPN. Before installing the module, disconnect the
ProCurve Secure Router from the power source. Slide the module into the
encryption slot in the ProCurve Secure Router's rear panel until the module
sits firmly against the chassis. Secure the screws and restore power to the
router. You should refer to the "Installation Instructions" in the ProCurve
Secure Router 7100/7200 IPSec Module Quick Start Guide for detailed
instructions on how to install the module.
The IPSec VPN module enables the software features that support IPSec
protocols and relieves the CPU of the overhead associated with processing
the encryption algorithms.
After installing the IPSec module, you will be able to enter crypto commands
in the CLI or use the VPN wizard in the Web browser interface.
