Lab 3-3: DHCP Server in Packet Tracer

In this lab, you will configure a DHCP server in Packet Tracer to assign IP's to laptops and workstations.

Configure DHCP server

• Rename the server to DHCP-01

• Go to the services tab and enable DHCP

• Change the Start Address of serverPool to 100 in the last octect

serverPool is the Default Pool and cannot be removed, you will use this pool for VLAN 1 Management

• Create a Pool for each of your FacStaff, Student, StuLab1, and StuLab2, VLANs

  • Default gateway is the router address for the VLAN

  • Leave DNS at 0.0.0.0

  • Start IP address—the first IP that you want to assign

  • Subnet mask for VLAN

  • Maximum Users: set this close to the requirements in your Subnet Table

  • TFTP leave at 0.0.0.0

Test your DHCP Server

• Add a workstation directly to East-Core-Switch on VLAN1 (FA0/4)

• Workstation should be able to get an IP address from the DHCP server!

  • Run ipconfig /renew

Configure DHCP Relay

• East-Core-Switch is the router for your VLANS (remember that DHCP requests are broadcasts and cannot cross a router without help)

• To get DHCP broadcasts from your user VLANs (100, 110, 130, 140), you need to tell the router to forward them to your DHCP server.

• This is done with the ip helper-address vlan interface configuration

• On East-Core-Swicth go into the interface configuration for FacStaff VLAN 100

  • config t

  • interface vlan 100

  • ip-helper-address 10.26.10.2

• Repeat for all VLANS (110, 130, 140)

Configure Clients to use DHCP

• Go into the configuration on all machines and change the gateway from static to DHCP

• Your devices should get DHCP addresses

• All your systems should be able to ping each other
