Address Translation

Overview/Description
To outline how NAT operates, and to configure NAT so as to reuse a limited number of available registered IP addresses for a private network

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
120 Minutes

Objectives:

Address Translation

  • recall the reasons why NAT is used, identify the advantages and disadvantages of NAT, and recognize essential NAT terms and concepts.
  • identify the different implementations of NAT and recall the processes involved in the translation of inside and outside addresses.
  • configure NAT to enable static and dynamic translation of inside and outside source addresses, and to handle overlapping networks.
  • use show commands to verify the correct operation of NAT, debug commands to identify specific operations in NAT, and clear commands to remove specific or all NAT entries.
  • configure static and dynamic NAT on a router in a given scenario.
  • recall the components that make up NAT, list the commands associated with NAT, and evaluate command output to determine how a given configuration operates.
