What are the advantages of using IPsec VPN?
IPsec Virtual Private Network (VPN) technology enables remote users to connect to private computer networks to gain access to their resources in a secure way. For example, an employee traveling or working from home can use a VPN to securely access the office network through the Internet.
What is the purpose of IPsec VPN configuration?
IPsec is a framework of open standards developed by the IETF. It provides security for the transmission of sensitive information over unprotected networks such as the Internet. IPsec acts at the network layer, protecting and authenticating IP packets between participating IPsec devices (“peers”), such as Cisco routers.
What is necessary to initiate the IPSec process?
This process requires that the IPSec systems first authenticate themselves to each other and establish ISAKMP (IKE) shared keys. A security association (SA) is a relationship between two or more entities that describes how the entities will use security services to communicate securely.
What are the prerequisites for configuring a Cisco IPsec VPN?
VPN configuration information must be configured on both endpoints; for example, on your Cisco router and at the remote user, or on your Cisco router and on another router. You must specify parameters, such as internal IP addresses, internal subnet masks, DHCP server addresses, and Network Address Translation (NAT).
Introduction
This document describes how to configure a policy-based VPN (site-to-site) over Internet Key Exchange (IKEv1) between two Cisco routers (Cisco IOS or Cisco IOS XE), which allows users to access resources across the sites over an IPsec VPN tunnel. cisco.com
Prerequisites
Requirements There are no specific requirements for this document. Components Used The information in this document is based on a Cisco router with Cisco IOS®Release 15.7.
