Inter-VLAN-Routing-Router-on-a-Stick-

Configured inter-VLAN routing using router-on-a-stick architecture with VLAN segmentation, trunk links, and subinterfaces to enable communication between isolated networks.

🧪 Inter-VLAN Routing Lab (Router-on-a-Stick)

📌 Overview

This lab demonstrates inter-VLAN routing using a router-on-a-stick setup in Cisco Packet Tracer. It simulates an enterprise network with VLAN segmentation and routing between departments.

---

🎯 Objectives

• Create and assign VLANs on a switch
• Configure trunk link to router
• Set up router subinterfaces (802.1Q)
• Enable communication between VLANs

---

🧱 Topology

• 1 Router
• 1 Switch
• 2 PCs
• Router connected to switch via trunk link

---

🌐 VLANs & IPs

• VLAN 10 → 192.168.10.0/24 (PC1: 192.168.10.10)
• VLAN 20 → 192.168.20.0/24 (PC2: 192.168.20.10)
• Gateways:
  • 192.168.10.1
  • 192.168.20.1

---

⚙️ Key Configuration

• VLANs created on switch
• Access ports assigned to VLANs
• Trunk configured between switch and router
• Router subinterfaces configured for each VLAN

---

🧪 Test

• Ping between VLANs confirms inter-VLAN routing is working

---
