Overview

Introduction

Welcome to the Configure and Verify IPv4 and IPv6 Access Lists for Traffic Filtering Practice Lab. In this module you will be provided with the instructions and devices needed to develop your hands-on skills.

Learning Outcomes

In this module, you will complete the following exercises:

  • Configuring standard and extended access lists for IPv4
  • Configuring named access-lists for IPv4
  • Configuring and modifying IPv6 access-lists

After completing this lab, you will be able to:

  • Create Standard Access-Lists in IPv4
  • Create an Extended Access-List in IPv4
  • Configure a Named Access-List

Exam Objectives

The following exam objectives are covered in this lab:

  • CAS-003 2.1 Analyze a scenario and integrate network and security components, concepts and architectures to meet security requirement.

Lab Duration

It will take approximately 1 hour to complete this lab.

Exercise 1 - Configuring Standard and Extended Access Lists using IPv4

Access Control Lists (ACLs) are used to control permissions on a specific object. For example, if you need to provide access to a file on a system to a specific user, then you can use ACLs to do this. In the similar context, on the routers and switches, ACLs can be used to define the flow of traffic. In this exercise, you will configure access control lists (ACLs) to control traffic flows through the network.

Learning Outcomes

After completing this exercise, you will be able to:

  • Create Standard Access Lists in IPv4
  • Create an Extended Access-List in IPv4

Exercise 2 - Configuring Named Access Lists Using IPv4

In the previous exercise, you configured standard and extended numbered access lists. In this exercise, you will create the same access lists, but this time, they will be named.

Learning Outcomes

After completing this exercise, you will be able to:

  • Configure a Named Access-List

Exercise 3 - Creating Access-Lists in IPv6

IPv6 access lists do not come in standard and extended forms in the same way that IPv4 access lists do. When defining IPv6 access lists, you must define both source and destination addresses or networks. Also, IPv6 access lists must be defined using a name and not a number.

Other than these differences, the logic behind access lists in IPv6 is virtually identical to that of IPv4.

In this task, you will configure IPv6 access lists on the NYEDGE1 router.

Learning Outcomes

In this module, you will complete the following exercises:

  • Configure and modify IPv6 access-lists
