Inter-VLAN Routing with Multilayer Switch

This project demonstrates Inter-VLAN Routing using a multilayer switch in Cisco Packet Tracer. It includes the creation and configuration of multiple VLANs, trunking, routing between VLANs, and DHCP-based IP assignment to end devices.

🧱 Network Topology

• VLANs: 10 (Engineer), 20 (Sales), 30 (Account)
• Switches: 4 Access Switches (Switch4 to Switch7) connected to a Multilayer Switch
• Multilayer Switch: Performs routing between VLANs and acts as DHCP server
• End Devices: PCs assigned to each VLAN based on port configuration

⚙️ Configuration Summary

VLANs

VLAN ID	Name	Purpose
10	Engineer	Engineering Dept
20	Sales	Sales Dept
30	Account	Accounting Dept

Multilayer Switch

• SVIs configured for each VLAN with IP addresses:
  • VLAN 10 → 192.168.10.1/24
  • VLAN 20 → 192.168.20.1/24
  • VLAN 30 → 192.168.30.1/24
• ip routing enabled for Inter-VLAN Routing
• DHCP Pools configured for each VLAN subnet
• Each VLAN interface includes ip helper-address if needed

Access Switches

• VLANs created and assigned to ports connected to end devices
• Trunk ports configured towards the Multilayer Switch

End Devices

• All end devices obtain their IP addresses dynamically via the DHCP server configured on the multilayer switch.
• Devices can communicate with others in different VLANs through Inter-VLAN Routing

✅ Verification

• ping between devices in different VLANs
• show ip interface brief to verify SVI status
• show vlan brief to verify VLAN-port assignments
• show ip dhcp binding to verify IP assignment via DHCP
