NETWORKING PRACTICAL FULL LAB

 

🧪 NETWORKING PRACTICAL LAB

🎯 Scenario

You are designing a small campus network with:

• 2 Routers
• 2 Switches
• 4 PCs
• VLANs + Routing + DHCP

 

🗺️ TOPOLOGY DIAGRAM

🌐 IP ADDRESSING PLAN

Device	Interface	IP Address
R1	G0/0	192.168.10.1
R1	G0/1	10.0.0.1
R2	G0/0	192.168.20.1
R2	G0/1	10.0.0.2

 

🧩 VLAN CONFIGURATION

VLAN	Name	Network
10	HR	192.168.10.0/24
20	IT	192.168.20.0/24

 

⚙️ STEP-BY-STEP CONFIGURATION

 

🔹 1. SWITCH CONFIGURATION (SW1 & SW2)

Create VLANs

enable

configure terminal

 

vlan 10

name HR

 

vlan 20

name IT

 

Assign Ports

interface fa0/1

switchport mode access

switchport access vlan 10

 

interface fa0/2

switchport mode access

switchport access vlan 20

 

Configure Trunk

interface fa0/24

switchport mode trunk

switchport trunk allowed vlan 10,20

 

🔹 2. ROUTER R1 CONFIGURATION

enable

configure terminal

 

interface g0/0

ip address 192.168.10.1 255.255.255.0

no shutdown

 

interface g0/1

ip address 10.0.0.1 255.255.255.252

no shutdown

 

🔹 3. ROUTER R2 CONFIGURATION

enable

configure terminal

 

interface g0/0

ip address 192.168.20.1 255.255.255.0

no shutdown

 

interface g0/1

ip address 10.0.0.2 255.255.255.252

no shutdown

 

🔹 4. STATIC ROUTING

On R1

ip route 192.168.20.0 255.255.255.0 10.0.0.2

On R2

ip route 192.168.10.0 255.255.255.0 10.0.0.1

 

🔹 5. DHCP CONFIGURATION (R1)

ip dhcp excluded-address 192.168.10.1

 

ip dhcp pool HR

network 192.168.10.0 255.255.255.0

default-router 192.168.10.1

 

🔹 6. PC CONFIGURATION

👉 Set PCs to DHCP mode

OR manually:

PC	IP	Gateway
PC1	192.168.10.2	192.168.10.1
PC2	192.168.20.2	192.168.20.1

 

🔍 TESTING (VERY IMPORTANT)

Run these commands:

ping 192.168.20.2

ping 192.168.10.2

✔ All PCs should communicate successfully.
