CTT-TAC: Intro to Routing and Access Lists


Start Here

Detailed Information

This module provides information on the fundamentals of routing. It introduces the routing protocols, Routing Information Protocol (RIP) and Interior Gateway Routing Protocol (IGRP), and teaches the basics of access lists. It is accompanied by a series of labs designed to enhance the concepts being explained. These labs give you the opportunity to apply what is being taught by using a simulated Cisco IOSĀ® Software environment.


  • Describe the concepts administrative distance and path determination
  • Describe a RIP routing table
  • Give examples of routing update reduction methods
  • Describe and configure default gateway and default routing
  • Explain the RIP metric and discuss its advantages and disadvantages
  • Recognize the roles of RIP timers
  • Differentiate between RIP Version 1 and RIP Version 2
  • Analyze administrative distances and determine which protocols take precedence
  • Configure the RIP routing protocol in a network
  • Use the basic commands necessary to maintain and troubleshoot RIP in Cisco IOS software
  • Define and describe IGRP-based routing operations
  • Describe the IGRP timers
  • Identify the types of IGRP routing updates and route advertisements
  • Configure the IGRP routing protocol in a network
  • Configure standard and extended IP access lists
  • Apply access lists and verify the consequences of filtered IP access
