Advanced Packet Tracer Scenario 1: Implementing VLANs and Inter-VLAN Routing

Scenario Description

In this scenario, you are tasked with designing a network for a medium-sized organization. The network consists of three departments: Sales, HR, and IT. Each department must be on its own VLAN for security and management purposes. Additionally, inter-VLAN communication is required to allow departments to share resources.

Requirements

1. Create three VLANs: Sales (VLAN 10), HR (VLAN 20), and IT (VLAN 30).

2. Configure a router to provide inter-VLAN routing.

3. Ensure all devices within a VLAN can communicate with each other.

4. Enable inter-VLAN communication.

Solution

Step 1: Network Design

1. Switch Configuration:

   • Connect all devices to a central switch.

   • Assign appropriate VLANs to each switch port based on the department.

2. Router Configuration:

   • Use a router with sub-interfaces to route traffic between VLANs.

   • Configure the router with IP addresses for each VLAN.

Step 2: Switch Configuration

1. Create VLANs:

   Switch(config)# vlan 10Switch(config-vlan)# name SalesSwitch(config-vlan)# vlan 20Switch(config-vlan)# name HRSwitch(config-vlan)# vlan 30Switch(config-vlan)# name IT

2. Assign Ports to VLANs:

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

Step 3: Router Configuration

1. Configure Sub-Interfaces for Inter-VLAN Routing:

   Router(config)# interface fa0/0.10Router(config-subif)# encapsulation dot1Q 10Router(config-subif)# ip address 192.168.10.1 255.255.255.0Router(config)# interface fa0/0.20Router(config-subif)# encapsulation dot1Q 20Router(config-subif)# ip address 192.168.20.1 255.255.255.0Router(config)# interface fa0/0.30Router(config-subif)# encapsulation dot1Q 30Router(config-subif)# ip address 192.168.30.1 255.255.255.0

2. Enable Routing:

   Router(config)# ip routing

Step 4: Verify Configuration

1. Check VLANs on Switch:

   Switch# show vlan brief

2. Check Router Sub-Interfaces:

   Router# show ip interface brief

3. Test Connectivity:

   • Ping between devices within the same VLAN.

   • Ping between devices in different VLANs to verify inter-VLAN routing.

By following these steps, you successfully implement VLANs and inter-VLAN routing in Packet Tracer. This setup ensures secure and efficient communication between departments.

Advanced Packet Tracer Scenario 2: Configuring OSPF in a Multi-Area Network

Scenario Description

You are tasked with configuring a multi-area OSPF network for a large enterprise. The network is divided into three areas: Area 0 (backbone), Area 1, and Area 2. Each area contains multiple routers and networks. The goal is to ensure efficient routing and redundancy within and between areas.

Requirements

1. Configure OSPF on all routers.

2. Assign appropriate OSPF areas to each router interface.

3. Ensure OSPF routing is operational and efficient.

4. Implement redundancy within the OSPF configuration.

Solution

Step 1: Network Design

1. Assign IP Addresses:

   • Allocate IP addresses to each router interface.

   • Ensure IP addresses are unique within the network.

2. OSPF Area Configuration:

   • Define which interfaces belong to which OSPF areas.

Step 2: Router Configuration

1. Configure OSPF on Routers:

   Router(config)# router ospf 1Router(config-router)# network 192.168.1.0 0.0.0.255 area 0Router(config-router)# network 192.168.2.0 0.0.0.255 area 1Router(config-router)# network 192.168.3.0 0.0.0.255 area 2

2. Assign OSPF Areas:

   Router(config)# interface fa0/0Router(config-if)# ip ospf 1 area 0Router(config)# interface fa0/1Router(config-if)# ip ospf 1 area 1Router(config)# interface fa0/2Router(config-if)# ip ospf 1 area 2

Step 3: Ensure Redundancy

1. Configure OSPF for Redundancy:

   • Ensure multiple paths are available for routing.

   • Use the cost command to influence path selection.

   Router(config-router)# network 192.168.4.0 0.0.0.255 area 0Router(config)# interface fa0/3Router(config-if)# ip ospf cost 10

Step 4: Verify OSPF Configuration

1. Check OSPF Neighbors:

   Router# show ip ospf neighbor

2. Check OSPF Routes:

   Router# show ip route ospf

3. Test Network Connectivity:

   • Ping between routers in different areas.

   • Verify that the OSPF routing table is updated correctly.

By implementing this multi-area OSPF configuration, you ensure that the network is scalable, efficient, and redundant. This setup is ideal for large enterprises with complex routing needs.
