Cisco Packet Tracer remains one of the most effective network simulation tools for mastering practical networking skills. From configuring dynamic routing to troubleshooting complex network layers, it gives students real-world experience in a simulated environment. However, as the complexity of assignments increases, many students struggle with integrating multiple protocols, interpreting multi-layer topology outputs, or validating simulation logic. It’s no surprise that many learners search online with queries like do my packet tracer assignment to get through the difficult concepts and deliver accurate solutions.

At ComputerNetworkAssignmentHelp.com, we assist students at all levels—from beginners to those pursuing CCNA and advanced networking certifications. Our experts not only offer complete assignments but also explain the logic behind every solution. In this post, we will walk you through two expert-designed master-level Packet Tracer tasks, complete with step-by-step implementation and validation.

Task 1: Configure an Enterprise Network with VLANs, Trunking, and Inter-VLAN Routing

Scenario

You are working as a network engineer for a medium-sized enterprise that has grown significantly in recent months. The organization now wants to divide its network into departments using VLANs. However, communication must still occur across VLANs for administrative tasks, shared databases, and VoIP configurations. Your objective is to design and configure a secure, segmented network using VLANs and inter-VLAN routing.

Requirements

  • Create 3 VLANs: HR, Sales, and IT

  • Assign PCs to respective VLANs based on port assignment

  • Configure a Layer 3 switch for inter-VLAN routing

  • Implement trunking between access switches and the core switch

  • Ensure each VLAN can communicate with others through the Layer 3 switch

Solution Steps

Step 1: Define the VLANs

bash

CopyEdit

Switch(config)# vlan 10 Switch(config-vlan)# name HR Switch(config-vlan)# exit Switch(config)# vlan 20 Switch(config-vlan)# name Sales Switch(config-vlan)# exit Switch(config)# vlan 30 Switch(config-vlan)# name IT Switch(config-vlan)# exit

Step 2: Assign VLANs to Interfaces

bash

CopyEdit

Switch(config)# interface range fa0/1 - 5 Switch(config-if-range)# switchport mode access Switch(config-if-range)# switchport access vlan 10 Switch(config)# interface range fa0/6 - 10 Switch(config-if-range)# switchport mode access Switch(config-if-range)# switchport access vlan 20 Switch(config)# interface range fa0/11 - 15 Switch(config-if-range)# switchport mode access Switch(config-if-range)# switchport access vlan 30

Step 3: Configure Trunk Ports on Both Access and Core Switches

bash

CopyEdit

Switch(config)# interface gi0/1 Switch(config-if)# switchport mode trunk Switch(config-if)# switchport trunk allowed vlan 10,20,30

(Repeat for all switches that connect to the core.)

Step 4: Setup Inter-VLAN Routing on the Layer 3 Switch

bash

CopyEdit

L3Switch(config)# interface vlan 10 L3Switch(config-if)# ip address 192.168.10.1 255.255.255.0 L3Switch(config-if)# no shutdown L3Switch(config)# interface vlan 20 L3Switch(config-if)# ip address 192.168.20.1 255.255.255.0 L3Switch(config-if)# no shutdown L3Switch(config)# interface vlan 30 L3Switch(config-if)# ip address 192.168.30.1 255.255.255.0 L3Switch(config-if)# no shutdown

Enable routing:

bash

CopyEdit

L3Switch(config)# ip routing

Step 5: Test Connectivity

Use the ping command from PCs in different VLANs to verify communication:

bash

CopyEdit

PC> ping 192.168.20.1 PC> ping 192.168.30.1

Expert Commentary

This Packet Tracer challenge reflects real-world enterprise demands. The implementation of VLANs ensures traffic segmentation and security, while inter-VLAN routing maintains communication efficiency. Common issues students face in this task include missing trunk configurations, incorrect VLAN IDs, or forgetting to enable IP routing on the Layer 3 switch. These small gaps can render the entire setup non-functional.

Task 2: Implement OSPF in a Multi-Area Topology with Router-on-a-Stick Configuration

Scenario

A company has grown geographically and now operates in three separate office buildings connected via routers. To optimize routing updates and reduce overhead, you are tasked with implementing a multi-area OSPF configuration. Each branch office has multiple VLANs configured through Router-on-a-Stick (RoS) setup. The objective is to maintain route summarization and minimize convergence time.

Requirements

  • Configure OSPF with at least two areas

  • Implement Router-on-a-Stick for VLANs in each office

  • Ensure full connectivity between VLANs across different buildings

  • Apply passive-interface for unnecessary OSPF advertisements

  • Test convergence and route summarization

Solution Steps

Step 1: Configure VLAN Interfaces (Sub-Interfaces) on the Router

For Office 1 router:

bash

CopyEdit

Router(config)# interface g0/0.10 Router(config-subif)# encapsulation dot1Q 10 Router(config-subif)# ip address 10.1.10.1 255.255.255.0 Router(config)# interface g0/0.20 Router(config-subif)# encapsulation dot1Q 20 Router(config-subif)# ip address 10.1.20.1 255.255.255.0

Repeat similar configuration for Office 2 and Office 3, using distinct subnet ranges.

Step 2: Enable OSPF on Each Router

Office 1 Router:

bash

CopyEdit

Router(config)# router ospf 1 Router(config-router)# network 10.1.10.0 0.0.0.255 area 1 Router(config-router)# network 10.1.20.0 0.0.0.255 area 1 Router(config-router)# network 192.168.1.0 0.0.0.255 area 0

Office 2 Router:

bash

CopyEdit

Router(config)# router ospf 1 Router(config-router)# network 10.2.10.0 0.0.0.255 area 2 Router(config-router)# network 10.2.20.0 0.0.0.255 area 2 Router(config-router)# network 192.168.1.0 0.0.0.255 area 0

Core Router (connected to both office routers):

bash

CopyEdit

Router(config)# router ospf 1 Router(config-router)# network 192.168.1.0 0.0.0.255 area 0

Step 3: Apply Passive Interface to Reduce Overhead

bash

CopyEdit

Router(config-router)# passive-interface default Router(config-router)# no passive-interface g0/0

(Apply only on interfaces where dynamic neighbor discovery is required.)

Step 4: Verify OSPF Neighbor Relationships

bash

CopyEdit

Router# show ip ospf neighbor

Ensure all routers show established neighbor adjacencies.

Step 5: Test Route Summarization and Propagation

You can test summarization using the show ip route command to verify that summarized routes from one area are visible in another.

bash

CopyEdit

Router# show ip route ospf

Expert Commentary

This setup represents a foundational skill expected from CCNA and network engineering students. Proper area segmentation in OSPF helps limit SPF recalculations. Mistakes often occur in wildcard mask configurations, or missing encapsulation dot1Q commands. Another challenge students face is understanding when and where to apply passive interfaces. In large networks, these details make a significant difference in performance and stability.

Key Takeaways from Both Scenarios

These two Packet Tracer exercises highlight core competencies required in real-world networking:

  1. Layer 2 and Layer 3 Integration: Knowing how to bridge switching and routing functionalities using VLANs and inter-VLAN routing is critical.

  2. Routing Protocol Mastery: OSPF, especially in multi-area configurations, demonstrates an understanding of scalable, hierarchical network design.

  3. Protocol Optimization: Using features like passive-interface and summarization ensures networks are efficient and stable.

  4. Troubleshooting Skills: Even when configuration seems correct, things like mismatched trunk settings or missed subnet declarations can break the network.

Why Expert Help Matters

Assignments involving tasks like these require students to blend theoretical knowledge with practical execution. While the concept of subnetting or VLANs might appear straightforward on paper, implementing them in a Packet Tracer environment can be challenging. Missteps as minor as a missing IP address or forgetting a no shutdown command can cause hours of frustration. This is where expert intervention can help learners not only finish their work but truly understand it.
