Basic Network Configuration using Cisco Packet Tracer

Overview

• Configuration of a basic network with:
  • 4 PCs
  • 2 Switches
  • 1 Router
• Connection method: Copper Straight Through Cable

Steps for Configuration

1. Connecting Devices

• Connect PCs to Switches
• Connect Switches to Router using Gigabit Ethernet ports
• Initial status: Red lights indicating no connection

2. Configuring the Router Ports

• Enter CLI mode:
  • Prompt: Would you like to enter the initial configuration dialog? (Type: Yes)
  • Type:
    • enable (Enter)
    • configure terminal (Enter)
• Configure interface:
  • Type: interface g0/0 (Enter)
  • Assign IP address:
    • Format: ip address <IP> <subnet mask>
    • Example: ip address 1.1 255.255.255.0
  • Type: no shutdown (Enter)
  • Result: Interface g0/0 state changes to up
• Exit interface mode

3. Configuring Additional Interface

• Configure the second interface:
  • Type: interface g0/1 (Enter)
  • Similar steps to assign IP and bring it up
• Check status: Red lights change to green

4. Configuring the PCs

• Click on each PC > Go to Desktop > IP Configuration
• Assign IP Addresses and Default Gateway:
  • PC1:
    • IP: 1.10
    • Default Gateway: 192.168.1.1
  • PC2:
    • IP: 1.11 (for example)
    • Default Gateway: 192.168.1.1
  • PC3:
    • IP: 2.10
    • Default Gateway: 2.1
  • PC4:
    • IP: 2.11 (for example)
    • Default Gateway: 2.1

5. Testing the Connection

• Allow some time for tables to update
• Test connectivity:
  • PC to Router: Successful
  • Cross-network (from PC1 to PC3): Successful

Conclusion

• Successfully established a basic network configuration with functional connections.
