How to configure DHCP on Cisco packet tracer

Configuring DHCP on a Cisco router in Packet Tracer is an essential skill for network students. It automates IP address assignment, making network management more efficient. In this guide, we will setup DHCP on a router. This setup will provide automatic IP addresses to client PCs.

These PCs are connected via a switch. Our setup includes a router (Router0) that is configured to act as a DHCP server. A switch (Switch01) provides connectivity, and there are two client PCs (PC0 and PC1). The router will use the 192.168.1.0/24 network to allocate IP addresses.

Let’s dive into the configuration!

Network Setup and Configuration Plan

• Router (Router0): This device will be configured to provide DHCP.
• Router Interface (Gi0/0): Connected to Switch01 (IP address range 192.168.1.0/24).
• Switch (Switch01): Acts as the central device to connect PCs to the router.
• Switch Port Gi0/1: Connects to Router0 (Gi0/0).
• Switch Port Fa0/1: Connects to PC0.
• Switch Port Fa0/2: Connects to PC1.
• DHCP Scope: The router will distribute IP addresses from 192.168.1.1 to 192.168.1.254 with a /24 subnet mask.

Step Configuration Cisco Packet Tracer

1. Connect Devices:

• Connect Router0’s Gi0/0 interface to Switch01’s Gi0/1 port using a copper straight-through cable.
• Connect PC0 to Switch01’s Fa0/1 port and PC1 to Switch01’s Fa0/2 port.

1. Configure the Router (Router0):

• Select Router0, then go to the CLI tab.
• Enter global configuration mode:
  enable configure terminal Set host name on Router

1. Configure Interface Gi0/0 on Router0:

• Assign an IP address to the Gi0/0 interface in the 192.168.1.0/24 network:
• interface gigabitEthernet 0/0
• ip address 192.168.1.1 255.255.255.0
• no shutdown
• exit

1. Enable DHCP on the Router:

• Define the DHCP pool and configure the IP address range:
• ip dhcp pool LAN-network
• 192.168.1.0 255.255.255.0
• default-router 192.168.1.1
• dns-server 8.8.8.8 exit
• Here, we define a DHCP pool named LAN_POOL. The router will assign IP addresses within 192.168.1.0/24 and set 192.168.1.1 as the default gateway, while 8.8.8.8 is configured as the DNS server.

1. Exclude the Router IP Address from the DHCP Pool (to avoid conflicts):

• Exclude 192.168.1.1 to reserve it for the router itself. Now I excluded some IP addresses to use with static devices. The PCs will start from DHCP from 192.168.1.11
  Howto-R(config)#ip dhcp excluded-address 192.168.1.1 192.168.1.10

1. Verify DHCP Configuration:

• Exit configuration mode and verify DHCP setup:
  show ip dhcp pool
• show ip dhcp binding

1. Configure the Clients (PC0 and PC1):

• On PC0 and PC1 in Packet Tracer:
  • Open the Desktop tab.
  • Select IP Configuration.
  • Choose DHCP for IP settings.
• After a moment, each PC should receive an IP address from the 192.168.1.0/24 range. Verify that PC0 and PC1 have IP addresses within the range, with 192.168.1.1 as the default gateway.

1. Test Connectivity:

• On either PC0 or PC1, go to the Command Prompt in the Desktop tab.
• Test connectivity by pinging the router at 192.168.1.1:
  ping 192.168.1.1
• Successful replies confirm that the DHCP configuration is working correctly, and the PCs are receiving IP addresses automatically.

This hands-on example shows how to configure DHCP on a Cisco router in Packet Tracer. It simplifies the process of assigning IP addresses automatically to client devices on a network. DHCP is a valuable tool for simplifying network management, especially in larger networks.
