Computer science it infrastructure elementary protocols assignment | BMIS 520 – IT Infrastructure | Liberty University

1. Unzip the file PacketTracerAndLabs.zip under “IT Infrastructure Project Assignments”.

1. In the zip file PacketTracerAndLabs.zip, install Packet Tracer using the .exe file “Cisco Packet Tracer 6.2 for Windows Student Version.exe”.

1. Open the PDF in the zip file for an introduction to Packet Tracer.

1. You must use the Packet Tracer version 6.2, provided in the Project instructions zip file. Instructors cannot open other versions due to licensing and will not be able to open incompatible versions, resulting in loss of points.

1. Take progressive screenshots that show completion of your work in Packet Tracer. Please see the example screenshot for how to create proper screenshots for your assignments and projects.

1. Leave all passwords blank on devices in Packet Tracer so that your assignment can be graded properly.

1. Complete all assignment deliverables in one (1) Cisco Packet Tracer file.

1. Submit your one (1) Packet Tracer file for credit.

1. Submit one (1) Microsoft Word document with your honesty statement, compliant screenshots, and all references used. 

1. Submit each file individually – no compressed or zipped files will be received for credit.

1. Open a brand new Cisco Packet Tracer file.

2. Create the assignment network topology in Cisco Packet Tracer.

3. Create a minimum of four (4) local area networks (LANs).

4. Each LAN requires a minimum of one (1) switch and two (2) laptops/PCs.

5. Use proper NIC hardware for each port and assign proper cables between the devices.

6. Create a spreadsheet in Microsoft Excel and add this to your Microsoft Word document that shows all devices, interfaces, IP addresses, subnet masks, wildcard masks, default gateways and any other relevant information. For example:

7. Design and assign proper IP addresses per the topology to all NIC cards on the routers, switches, and PCs. Use efficient subnets. IPv4 or IPv6 can be used.

8. Label the NIC cards in Packet Tracer with their assigned IP addresses.

9. Try to ping the server from one of the PCs. It will not work unless the routing tables in the routers know the routes.

10. To ensure routing is working, add proper static routes for all LAN subnets.

11. Once static routing is correct, show proper screenshots that validate the network is completely functional. All devices should be able to communicate.

12. *Note, to provide hints and extra help a working example is provided at the end of this assignment with a topology and configurations.

*Note, these are only a few select examples of what should be learned prior to completing the assignment. This is not comprehensive. All relevant configurations are necessary from the textbook.

Saving configurations on a router:

Router modes when logging in:

IPv6 NIC assignment on interfaces:

IPv4 NIC assignment on interfaces:

To bring an interface up or enable it:

R4(CONFIG-IF)# no shutdown

To remove a configuration place “no” in front of the original command:

R4(CONFIG-IF)# no ip address 192.168.4.254

Static route assignment examples:

Once you have these examples completed, create the assignment network topology and apply what you have learned.

1. Add to and modify the part 1 Cisco Packet Tracer file as necessary.

2. Use proper NIC hardware for each port and assign proper cables between the devices.

3. Create a spreadsheet in Microsoft Excel that shows all devices, interfaces, IP addresses, subnet masks, wildcard masks, default gateways and any other relevant information. Add the spreadsheet to your Microsoft Word document. For example:

4. Design and assign proper IP addresses per the topology to all NIC cards on the routers, switches, and PCs. Use efficient subnets. IPv4 or IPv6 can be used.

5. Label the NIC cards in Packet Tracer with their assigned IP addresses.

6. Design, create, and implement four (4) VLANs for four (4) business departments such as the accounting department.

7. Name the VLANs starting with your first and last name, e.g. <Amy_Smith_Acct_VLAN>

8. Add the VLANs to four (4) routers and four (4) switches.

9. Ensure inter-VLAN routing is working by properly configuring four (4) VLANs to function across four unique routers.

10. Once this part of the assignment is correct, show proper screenshots that validate all of the latter deliverables are completely functional.

This is a step by step example for configuring a new VLAN in the final assignment network topology. Start by assigning numbers and VLAN descriptions to these numbers on your layer 2 switches:

SW1(config)# vlan 20

SW1(config-vlan)# name Sales

SW1(config-vlan)# vlan 30

SW1(config-vlan)# name HR

Next, configure these same VLANs on subsequent switches in your network. After your VLANs are configured on your switches, it is necessary to configure connecting routers.

Step by step example for configuring VLAN 1 on a Router using 801.1Q:

Let’s start by configuring a subinterface for VLAN 1. Create a subinterface on the next hop router connected to SW1. Use the interface connected to your switch. As an example, we can use G3/0 for VLAN 1 using 1 as the subinterface ID:

• Router(config)# interface g3/0.1

Note, if your router interface is different such as int G0/1, the command would be:

• Router(config)# interface g0/1.1

Next, we configure the subinterface to operate on VLAN 1 using 801.1Q encapsulation:

• Router(config-subif)# encapsulation dot1Q 1

Configure the subinterface with the IP address from the Address Table. Notice, this is often a default gateway IP address:

• Router(config-subif)# ip address 172.16.10.1 255.255.255.0

Note, if you get an error such as, “172.16.10.0 overlaps with GigabitEthernet3/0”. You need to remove your existing Gig3/0 IP address. As an example:

Router(config-subif)#exit

Router(config)#int Gig3/0

Router(config-if)#no ip address 172.16.10.0 255.255.255.0

Router(config-if)#shutdown

Now, reconfigure your subinterface correctly.

Next, let’s review some example solutions to help you get started.

Switch 0 configuration for Amy_Smith_Switch0:

interface Vlan1

ip address 172.16.10.5 255.255.255.0

ip default-gateway 172.16.10.1

spanning-tree mode pvst

spanning-tree extend system-id

interface FastEthernet0/1
