At ComputerNetworkAssignmentHelp.com, our professional team of networking experts provides comprehensive Packet Tracer solutions that not only fulfill academic requirements but also deepen conceptual understanding. In this post, we present two master-level Packet Tracer scenarios along with their detailed explanations and step-by-step solutions completed by one of our senior experts. These examples reflect the type of expertise and clarity we bring to every student’s assignment.

Master-Level Packet Tracer Scenario 1: Multi-Area OSPF Implementation with Inter-VLAN Routing and DHCP Services

Scenario Overview

In this scenario, students are required to design a multi-area OSPF topology that integrates VLAN segmentation and DHCP services. The topology consists of three routers operating in different OSPF areas, multiple switches configured with VLANs, and end devices that obtain IP configurations dynamically. The objective is to ensure full inter-area communication, proper DHCP allocation, and router-on-a-stick configuration for VLAN intercommunication.

This question assesses a student’s ability to:

  • Segment networks using VLANs.

  • Implement multi-area OSPF routing with appropriate area IDs and summarization.

  • Configure DHCP pools for each VLAN to provide dynamic IP addressing.

  • Verify connectivity across OSPF areas and VLANs.

This problem emphasizes conceptual clarity in routing protocols, switching fundamentals, and dynamic host configuration—key areas in advanced network design and administration.

Expert Approach and Design Logic

Before starting any configuration, our expert at ComputerNetworkAssignmentHelp.com emphasizes the importance of a structured design process:

  1. Network Planning and Addressing Scheme:
    Each OSPF area and VLAN is assigned a separate subnet. The addressing scheme is hierarchical, supporting future scalability. For example, Area 0 (Backbone) connects the core routers, while Area 1 and Area 2 connect departmental switches and hosts.

  2. Router Configuration Strategy:

    • All routers participate in OSPF.

    • Area 0 acts as the backbone.

    • Area 1 (Sales Department) and Area 2 (IT Department) connect via ABRs (Area Border Routers).

    • Inter-VLAN routing is configured on Router 1 using subinterfaces.

  3. DHCP Service Design:

    • The DHCP pools are configured on Router 1 for VLANs 10, 20, and 30.

    • Each VLAN gets its default gateway from the router subinterface.

  4. Verification Tests:

    • Ping tests across VLANs.

    • OSPF adjacency verification.

    • DHCP lease verification.

Step-by-Step Expert Solution

Step 1: VLAN Configuration on Switches

Our expert begins by defining VLANs on each switch and assigning ports to respective VLANs:

Switch1(config)# vlan 10
Switch1(config-vlan)# name Sales
Switch1(config)# vlan 20
Switch1(config-vlan)# name IT
Switch1(config)# vlan 30
Switch1(config-vlan)# name Admin
Switch1(config)# interface fa0/1
Switch1(config-if)# switchport mode trunk
Switch1(config)# interface range fa0/2 - 5
Switch1(config-if-range)# switchport mode access
Switch1(config-if-range)# switchport access vlan 10

This configuration ensures proper segmentation at Layer 2.

Step 2: Router-on-a-Stick Configuration

The router is connected to the switch through a trunk port, with each subinterface representing a VLAN.

Router1(config)# interface g0/0.10
Router1(config-subif)# encapsulation dot1Q 10
Router1(config-subif)# ip address 192.168.10.1 255.255.255.0
Router1(config)# interface g0/0.20
Router1(config-subif)# encapsulation dot1Q 20
Router1(config-subif)# ip address 192.168.20.1 255.255.255.0
Router1(config)# interface g0/0.30
Router1(config-subif)# encapsulation dot1Q 30
Router1(config-subif)# ip address 192.168.30.1 255.255.255.0

Now, the router can route traffic between VLANs (inter-VLAN routing).

Step 3: DHCP Configuration

Each VLAN is assigned a DHCP pool.

Router1(config)# ip dhcp pool VLAN10
Router1(dhcp-config)# network 192.168.10.0 255.255.255.0
Router1(dhcp-config)# default-router 192.168.10.1
Router1(dhcp-config)# dns-server 8.8.8.8
Router1(config)# ip dhcp pool VLAN20
Router1(dhcp-config)# network 192.168.20.0 255.255.255.0
Router1(dhcp-config)# default-router 192.168.20.1
Router1(dhcp-config)# dns-server 8.8.8.8

This ensures hosts automatically obtain IP configurations.

Step 4: OSPF Multi-Area Configuration

Each router is assigned to an appropriate OSPF area.

Router1(config)# router ospf 10
Router1(config-router)# network 192.168.10.0 0.0.0.255 area 1
Router1(config-router)# network 192.168.20.0 0.0.0.255 area 2
Router1(config-router)# network 10.0.0.0 0.0.0.3 area 0

Routers 2 and 3 are similarly configured to ensure adjacency formation and area separation.

Step 5: Verification and Testing

After configuration, our expert tests connectivity between devices across VLANs and areas. Using ping and show ip ospf neighbor, the expert verifies that:

  • OSPF adjacencies are formed successfully.

  • Hosts in different VLANs can communicate via inter-VLAN routing.

  • DHCP pools are distributing IPs correctly.

Result:
All connectivity tests succeed, proving the design is functional and efficient.

Expert Insights

This scenario demonstrates how advanced students can use Packet Tracer to emulate enterprise-like networks. Understanding how multi-area OSPF optimizes routing and how VLANs ensure segmentation helps students develop real-world network engineering skills.

Master-Level Packet Tracer Scenario 2: Implementing Network Redundancy Using EtherChannel and HSRP

Scenario Overview

This scenario aims to test a student’s grasp of redundancy, high availability, and load balancing within a campus LAN. The network includes two core switches and multiple access switches. The core switches connect to a router that provides gateway redundancy using HSRP (Hot Standby Router Protocol). The access links between core and access switches are bundled using EtherChannel to improve bandwidth and fault tolerance.

Students are expected to:

  • Implement Layer 2 redundancy using EtherChannel.

  • Configure HSRP to ensure gateway availability.

  • Verify load balancing and failover functionality.

Expert Design Strategy

The expert’s design philosophy focuses on minimizing downtime and maximizing link utilization. The approach includes:

  1. EtherChannel (Port Aggregation):
    Access switches connect to the core through EtherChannel groups using the LACP (Link Aggregation Control Protocol).

  2. HSRP Gateway Redundancy:
    Two core routers (or multilayer switches) share a virtual IP acting as the default gateway for all hosts.

  3. Testing Failover Mechanisms:
    One core device is intentionally disabled to confirm seamless transition to the standby router.

Step-by-Step Expert Solution

Step 1: EtherChannel Configuration

On Access Switch:

SwitchA(config)# interface range g0/1 - 2
SwitchA(config-if-range)# channel-group 1 mode active
SwitchA(config-if-range)# exit
SwitchA(config)# interface port-channel 1
SwitchA(config-if)# switchport mode trunk

On Core Switch:

SwitchC(config)# interface range g0/1 - 2
SwitchC(config-if-range)# channel-group 1 mode passive
SwitchC(config)# interface port-channel 1
SwitchC(config-if)# switchport mode trunk

EtherChannel ensures multiple links act as one logical connection.

Step 2: HSRP Configuration

On Core Switch 1:

SwitchC1(config)# interface vlan 10
SwitchC1(config-if)# ip address 192.168.10.2 255.255.255.0
SwitchC1(config-if)# standby 1 ip 192.168.10.1
SwitchC1(config-if)# standby 1 priority 110
SwitchC1(config-if)# standby 1 preempt

On Core Switch 2:

SwitchC2(config)# interface vlan 10
SwitchC2(config-if)# ip address 192.168.10.3 255.255.255.0
SwitchC2(config-if)# standby 1 ip 192.168.10.1

The virtual IP 192.168.10.1 serves as the default gateway.

Step 3: Testing Redundancy

The expert disables one core switch to observe failover:

  • Hosts continue to communicate without any noticeable downtime.

  • HSRP elects the secondary router as the new active gateway.

  • When the primary router returns, preemption restores it as the active device.

This confirms a seamless failover and high availability.

Expert Observations

Our expert highlights how combining EtherChannel and HSRP enhances both link-level and gateway-level redundancy. This kind of simulation prepares students for enterprise-grade network management where uptime and stability are non-negotiable.
