Packet Tracer Multi-Campus Companion

Configuring Serial links, SVI-based VLANs on L3 Switch, OSPF, and Wireless LAN Controllers.

Scenario Overview

In this Cisco Packet Tracer lab, you will configure a distributed multi-campus corporate network. The layout is structured into five distinct LANs and four WAN links:

  • Top Routers WAN: Labeled Router0, Router1, and Router2. They connect via Serial interfaces on the top path.
  • Secondary WAN Links: Labeled Router1 to Router3, and Router2 to Router4. They connect via Twisted Pair crossover cables (routed on Gigabit interfaces).
  • LAN Interfaces: All routers connect to their respective local switches/servers using the physical GigabitEthernet0/0/0 interface. Router-to-Router twisted pair connections are established on GigabitEthernet0/0/1.
  • VLAN SVI Configuration: The Cyber Network under Router3 contains two VLANs (VLAN 10 and VLAN 20) configured via **Switch Virtual Interfaces (SVIs)** directly on the 3560-24PS Multilayer Switch.
  • Wireless Services: A WLC-PT Wireless LAN Controller resides on the WAN Campus LAN (192.168.5.0/24) and manages LAP wireless APs. The SSID is Kable with passphrase Kable123.
Interactive Guide Directions: Solve the subnet boundaries in the **Subnet Planner** tab first. Once verified, input your custom IP selections in the **IP Assignments** tab to dynamically unlock Cisco IOS CLI configs for each device.

Interface IP Custom Assignments

Configure the exact IPs you want to assign to each interface. The system will double-check that your IPs are valid host addresses inside each subnet and that no conflicts occur.

Planner Lock: Please solve and verify the **Subnet Planner** tab first. Once verified, this panel will unlock!

IOS Command-Line Script Builder

Once your interface IP assignments have been successfully validated in the **IP Assignments** tab, the command-line codes will compile. Choose a device on the left to copy commands directly into Packet Tracer.

Configuration Locked: Please calculate your subnets and configure valid interface IPs first.

Wireless LAN Controller (WLC-PT) Setup Guide

The wireless local area network is managed by the standalone Cisco **WLC-PT Wireless LAN Controller0** situated in the WAN Campus subnet. Lightweight Access Points (LAPs) dynamically register with it to deploy the wireless network.

SSID Specifications: The SSID must be configured as Kable with WPA2-PSK security and key Kable123.

Step-by-Step WLC-PT Config:

  1. Click on the Wireless LAN Controller0 (WLC-PT) in the top campus network.
  2. Go to the Config tab in the device dialog window.
  3. Under the Left menu, choose LAN interface, set static IP 192.168.5.3, subnet mask 255.255.255.0, and default gateway 192.168.5.1.
  4. Navigate to **Wireless LANs** in the menu:
    • Click on **WLANs** or create a new SSID.
    • Set SSID Name to Kable.
    • Enable security: Select WPA2-PSK.
    • Input Key passphrase: Kable123.
  5. On the LAP-PT (LightWeightAccessPoint) in the AI network, make sure it is powered on (drag power adapter) and connected to the AI Switch. It will communicate with WLC0 to receive the SSID configuration automatically.
  6. On the client **Laptop0** in the AI network: Click it → **Desktop** → **PC Wireless** → **Connect** tab. Locate the SSID **Kable** and connect using passphrase **Kable123**. Select DHCP IP setup to verify dynamic address leasing.

Lab Verification Checklist

Carry out these manual verify checks in Cisco Packet Tracer. Mark off each task as you complete it to build up your overall completion percentage!

1. Connections & Inter-Router Ports Setup
  • Verify top routers R1-R0 and R0-R2 are cabled via red Serial connections. Check that clock rates are set properly on the DCE ends.
  • Ensure crossover twisted pair connections are plugged into the Gig0/0/1 ports for R1-R3 and R2-R4.
  • Verify LAN switch links plug into the Gig0/0/0 ports of R0, R1, R2, R3, and R4.
2. Cyber Switch VLANs & SVI routing
  • VLAN 10 and VLAN 20 database entries created on Cyber Switch (3560 MLS) and mapped to client access ports.
  • SVI interfaces configured on Cyber Switch (Interface Vlan10 and Interface Vlan20) with their respective verified gateways.
  • Verify that ip routing is enabled on the Cyber Switch to permit Layer 3 inter-VLAN forwarding.
3. OSPF Dynamic Routing
  • OSPF Process 1 is deployed on all five routers and the Cyber Multilayer Switch (using backbone Area 0).
  • Check routing tables using show ip route and neighbors via show ip ospf neighbor. Each router must learn the other networks.
4. Servers, DHCP Helper & Wifi Setup
  • Web, DNS, and DHCP servers statically configured inside the WAN campus network (192.168.5.0/24).
  • WLC-PT configured with management IP 192.168.5.3 and SSID Kable (WPA2-PSK key: Kable123).
  • Laptop0 successfully joins WLC0 wireless SSID and pulls an IP address via DHCP.
  • End-to-end connectivity test: Laptop0 can successfully ping the Web Server (192.168.5.2) and DNS Server (192.168.5.5).
