This project simulates an enterprise-level dual-stack network using Cisco Packet Tracer, with full VLAN segmentation, router-on-a-stick inter-VLAN routing, DHCPv4 & DHCPv6, and a mix of IPv4 static routing and IPv6 dynamic routing using OSPFv3.
🚀 Designed and implemented as part of my CCNA hands-on practice and portfolio development.
- Implement VLANs to segment departments (HR, IT, Finance, Admin)
- Configure 802.1Q trunk ports between routers and switches
- Use subinterfaces on routers to perform inter-VLAN routing
- Enable static routing for IPv4 and OSPF for IPv6
- Setup DHCPv4 and DHCPv6 servers on routers
- Ensure full IPv4 and IPv6 communication between devices in different VLANs
- 2 Routers: R1 and R2 (dual-stack configured)
- 4 Switches: SW1 to SW4
- 4 VLANs: VLAN 10 (HR), VLAN 20 (IT), VLAN 30 (Finance), VLAN 40 (Admin)
- Multiple PCs assigned to VLANs across all switches
- Trunk ports used to connect routers and switches
| Technology | Configuration |
|---|---|
| VLANs | VLAN 10, 20, 30, 40 on SW1–SW4 |
| Trunk Ports | Fa0/24, Gi0/1, Fa0/23 (where needed) |
| Subinterfaces | Router-on-a-stick using G0/0/1.x |
| Static Routing | For IPv4 |
| OSPFv3 | For IPv6 dynamic routing |
| DHCPv4 | Pool per VLAN with exclusions |
| DHCPv6 | Prefix-based pools with DNS config |
| IPv6 Routing | ipv6 unicast-routing + OSPF area 0 |
| VLAN | Interface | IPv4 Address | IPv6 Address | Purpose |
|---|---|---|---|---|
| 10 | G0/0/1.10 | 192.168.1.1/27 | 2001:10::1/64 | HR |
| 20 | G0/0/1.20 | 192.168.2.1/27 | 2001:20::1/64 | IT |
| 30 | G0/0/1.30 | 192.168.3.1/27 | 2001:30::1/64 | Finance |
| 40 | G0/0/1.40 | 192.168.4.1/27 | 2001:40::1/64 | Admin |
| VLAN | Interface | IPv4 Address | IPv6 Address | Purpose |
|---|---|---|---|---|
| 10 | G0/0/1.10 | 192.168.1.65/27 | 2001:10::2/64 | HR |
| 20 | G0/0/1.20 | 192.168.2.65/27 | 2001:20::2/64 | IT |
| 30 | G0/0/1.30 | 192.168.3.65/27 | 2001:30::2/64 | Finance |
| 40 | G0/0/1.40 | 192.168.4.65/27 | 2001:40::2/64 | Admin |
