In this post, we will walk you through two master-level Packet Tracer scenarios, providing detailed solutions to help you grasp the concepts and techniques required for successful network configuration and troubleshooting.
Scenario 1: Configuring a Multi-Area OSPF Network
Objective: Configure and verify a multi-area OSPF network, ensuring proper inter-area communication and efficient route propagation.
Network Topology:
Three routers (R1, R2, R3)
Three networks (Network A, Network B, Network C)
OSPF Areas: Area 0 (backbone), Area 1, and Area 2
Steps and Configuration:
Basic Router Configuration:
Configure the basic settings for each router, including hostname, interface IP addresses, and OSPF process initiation.
R1 Configuration:Router enableRouter# configure terminalRouter(config)# hostname R1Router(config)# interface GigabitEthernet0/0Router(config-if)# ip address 192.168.1.1 255.255.255.0Router(config-if)# no shutdownRouter(config-if)# exitRouter(config)# router ospf 1Router(config-router)# network 192.168.1.0 0.0.0.255 area 0Router(config-router)# exitR2 Configuration:Router enableRouter# configure terminalRouter(config)# hostname R2Router(config)# interface GigabitEthernet0/0Router(config-if)# ip address 192.168.2.1 255.255.255.0Router(config-if)# no shutdownRouter(config-if)# exitRouter(config)# router ospf 1Router(config-router)# network 192.168.2.0 0.0.0.255 area 1Router(config-router)# exitR3 Configuration:Router enableRouter# configure terminalRouter(config)# hostname R3Router(config)# interface GigabitEthernet0/0Router(config-if)# ip address 192.168.3.1 255.255.255.0Router(config-if)# no shutdownRouter(config-if)# exitRouter(config)# router ospf 1Router(config-router)# network 192.168.3.0 0.0.0.255 area 2Router(config-router)# exitInter-Area Communication:
Ensure routers in different areas can communicate by configuring Area Border Routers (ABRs).

Verify OSPF configuration and inter-area route propagation.
R1# show ip ospf neighborR2# show ip ospf neighborR3# show ip ospf neighborR1# show ip route ospfR2# show ip route ospfR3# show ip route ospf
Solution Explanation:
In this scenario, we configured a multi-area OSPF network with three routers, each connected to a distinct OSPF area. R1 and R2 were configured as ABRs to facilitate inter-area communication. Verifying the OSPF neighbors and routing tables ensured that routes from different areas were correctly propagated across the network, demonstrating a successful multi-area OSPF configuration.
Scenario 2: Implementing VLANs and Inter-VLAN Routing
Objective: Configure VLANs and inter-VLAN routing on a network with multiple switches and a router.
Network Topology:
Two switches (SW1, SW2)
One router (R1)
Three VLANs (VLAN 10, VLAN 20, VLAN 30)
Steps and Configuration:
Switch Configuration:
Configure VLANs on the switches and assign ports to each VLAN.
SW1 Configuration:Switch enableSwitch# configure terminalSwitch(config)# vlan 10Switch(config-vlan)# name SalesSwitch(config-vlan)# exitSwitch(config)# vlan 20Switch(config-vlan)# name EngineeringSwitch(config-vlan)# exitSwitch(config)# vlan 30Switch(config-vlan)# name HRSwitch(config-vlan)# exitSwitch(config)# interface range GigabitEthernet0/1 - 4Switch(config-if-range)# switchport mode accessSwitch(config-if-range)# switchport access vlan 10Switch(config-if-range)# exitSwitch(config)# interface range GigabitEthernet0/5 - 8Switch(config-if-range)# switchport mode accessSwitch(config-if-range)# switchport access vlan 20Switch(config-if-range)# exitSwitch(config)# interface range GigabitEthernet0/9 - 12Switch(config-if-range)# switchport mode accessSwitch(config-if-range)# switchport access vlan 30Switch(config-if-range)# exitSW2 Configuration:Switch enableSwitch# configure terminalSwitch(config)# vlan 10Switch(config-vlan)# name SalesSwitch(config-vlan)# exitSwitch(config)# vlan 20Switch(config-vlan)# name EngineeringSwitch(config-vlan)# exitSwitch(config)# vlan 30Switch(config-vlan)# name HRSwitch(config-vlan)# exitSwitch(config)# interface range GigabitEthernet0/1 - 4Switch(config-if-range)# switchport mode accessSwitch(config-if-range)# switchport access vlan 10Switch(config-if-range)# exitSwitch(config)# interface range GigabitEthernet0/5 - 8Switch(config-if-range)# switchport mode accessSwitch(config-if-range)# switchport access vlan 20Switch(config-if-range)# exitSwitch(config)# interface range GigabitEthernet0/9 - 12Switch(config-if-range)# switchport mode accessSwitch(config-if-range)# switchport access vlan 30Switch(config-if-range)# exitRouter Configuration:
Configure sub-interfaces on the router for each VLAN and enable inter-VLAN routing.

Solution Explanation:
In this scenario, we created three VLANs on two switches and assigned ports to each VLAN. On the router, we configured sub-interfaces for each VLAN and enabled inter-VLAN routing. This setup allows devices within each VLAN to communicate with devices in other VLANs, ensuring seamless inter-departmental connectivity within the network.
