Lab – Design and Build a Small Network (Answers Version)

Answers Note: Red font color or gray highlights indicate text that appears in the Answers copy only.

Objectives

Explain how a small network of directly connected segments is created, configured, and verified.

Background /Scenario

Note: This activity is best completed in groups of 2-3 students.

Design and build a network from scratch.

  • Your design must include a minimum of one Cisco 4321 router, two Cisco 2960 switches, and two PCs.
  • Fully configure the network and use IPv4 or IPv6 (subnetting must be included as a part of your addressing scheme).
  • Verify the network using at least five show commands.
  • Secure the network using SSH, secure passwords and console passwords (minimum).

Create a rubric to use for informal peer grading. Present your Capstone Project to the class and be able to answer questions from your peers and Answers!

Answers Note: This optional Modeling Activity is suggested to be a graded assignment after completing all the chapters. Students should be able to show how small networks are designed, configured, verified, and secured. Documentation is a large factor of this project and students must be able to explain their network design and verification using show commands.

Required Resources

  • Packet Tracer
  • Student/group-created rubric for assessment of the assignment

Answers will vary.

  1. Why do you think network documentation is so important to this activity and in the real world?

Type you answers here.

End of document

Documentation is imperative to good network management and without it, network administrators have to recreate topologies, physically check addressing, etc. This takes time, which could be used elsewhere.

A suggested rubric and documentation examples are provided below:

Note: This rubric includes a total of 100 points for the points earned category (if minimum standards are met). Answerss may wish to consider adding bonus points for additional/advanced work in any requirement category.

Requirement

Points Earned

Physical Topology – minimum 1 Cisco 4321 router, 2 Cisco 2960 switches, 2 PCs

(20 suggested)

Logical Addressing – subnetting used?

(20 suggested

Connectivity test – ping the router

(20 suggested)

Show commands (at least 5 documented as baseline)

(20 suggested)

Security – SSH, secure passwords, console security – documented by show running-configuration

(20 suggested)

Create a small network of directly connected segments, at a minimum 1 router, 2 switches and 2 PCs, and include a screenshot of the network in your final documentation.

The topology has 2 PCs, two switches, and a router.PC1 is connected to SW1 with a console cable to the router. PC2 is connected to SW2 and both SW1 and SW2 are connected to different interfaces of the router.

Configure the network to include switches, routers, and end devices and use your own network addressing.You must use subnetting of some type and you can use either IPv4 or IPv6 logical addressing. Create a table showing your physical addressing scheme for the router, switch, and PC and include it in your final documentation.

Verify the network by using show commands (at least 5) to provide a performance baseline. Be able to discuss why you chose the show commands you selected and what the output means (use all Packet Tracer activities for Chapters 1-17). Keep screenshots of your output and include in your final documentation.
