Preface

This preface describes the purpose, objectives, audience, organization, and conventions of

the Cisco 7100 Series VPN Conﬁguration Guide.

Purpose

This software conﬁgurationguide explains the basic tasksnecessary to conﬁgureIP-based,

multiservice intranet and extranet Virtual Private Networks (VPNs) on your Cisco 7100

series router that integrate security and quality of service (QoS) through network

technologies such as generic routing encapsulation (GRE) and IP Security Protocol (IPSec)

tunneling, and high-speed encryption to ensure private transactions over public data

networks. This guide does not cover every available feature; it is not intended to be a

comprehensive VPN conﬁguration guide. Instead, this guide simply explains the basic

tasks necessary to conﬁgure an intranet and extranet VPN on your Cisco 7100 series router

based on the GRE and IPSec tunneling protocols.

Note Although supported by Cisco 7100 series routers, this guide does not explainhow to

conﬁgure access VPNs using the Layer 2 Forwarding (L2F) or Layer 2 Tunnel Protocol

(L2TP) tunneling protocols. Conﬁguring access VPNs using the L2TP tunneling protocol

will be covered in a later release of this guide. For detailed information on conﬁguring

client-initiated and network access server (NAS)-initiated access VPNs using the L2F

tunneling protocol, refer to the Access VPN Solutions Using Tunneling Technology

publication.
