Virtual Private Networks

Overview/Description
To recall the fundamental concepts of VPNs and tunneling, to define commonly used VPN terms, and to recall the fundamental concepts and operations used in Cisco IOS cryptosystems for encryption, authentication, and key management

Target Audience
Network engineers responsible for configuring, implementing, troubleshooting, and managing WAN and remote access solutions; network architects responsible for designing WAN and remote access solutions; CCNP candidates; CCIE candidates

Prerequisites
A knowledge of general networking terms and concepts; experience in general Cisco router operation and configuration, including TCP/IP, routing protocols (RIP, IGRP), routed protocols (IP, IPX), standard and extended access lists, PPP operation and configuration over serial links, Frame Relay operation and configuration on interfaces and subinterfaces, and legacy DDR over ISDN-BRI operation and configuration; a basic knowledge of data networking equivalent to the information in the Cisco Certified Network Associate Basics (CCNAB) v2.0 course and the Interconnecting Cisco Network Devices (ICND) v2.0 course; experience working in a network environment is recommended

Expected Duration
100 Minutes

Objectives:

Virtual Private Networks

  • define VPN and identify the advantages of its applications over alternative WAN access technologies.
  • identify the main components or attributes of VPN implementations and select the best VPN technology for providing network connectivity for VPN design scenarios.
  • list the various encryptions, authentications, hash functions, and key management systems used in cryptography and recall key points in their operations.
  • recall how IPSec operates, list the differences in how the ESP and AH are applied using transport mode and tunnel mode, and outline the concepts of security associations.
  • select appropriate protocols and encryption technologies for a VPN solution.
