Cisco ICND2 1.1: VPN and Point-to-Point WAN Connections
This course is included in our On-demand training solution.
Cisco virtual private network (VPN) solutions provide an Internet-based WAN infrastructure for connecting branch offices, home offices, business partner sites, and remote telecommuters to all or portions of a company network. With cost-effective, high-bandwidth Internet connectivity that is secured by encrypted VPN tunnels, you can reduce WAN bandwidth costs while increasing connectivity speeds.
By integrating advanced network intelligence and routing, Cisco VPNs reliably transport complex mission-critical traffic, such as voice and client-server applications, without compromising communications quality or security. This course describes the uses of VPNs for site-to-site and remote-user access and the benefits of VPN implementations and the underlying hardware, software, and protocols that are required to configure a VPN solution are also covered.
One of the most common types of WAN connection is the point-to-point connection. Point-to- point connections are used to connect LANs to service provider WANs, and to connect LAN segments within an enterprise network. A LAN-to-WAN point-to-point connection is also referred to as a serial connection or leased-line connection. Wide-area networking services are typically leased from a service provider. Some WAN services operate as Layer 2 connections between your remote locations and are typically provided by a telephone company (telco) provider over its WAN switches.
Point-to-Point Protocol (PPP) emerged as an encapsulation protocol for transporting IP traffic over point-to-point (leased line) serial connections. PPP encapsulation has been carefully designed to retain compatibility with most commonly used supporting hardware. This course describes the operation, configuration, and verification of PPP.
