Configuring DHCP

Enable DHCP and Create pools

• Once you have established a server in packet tracer that you want to focus on DHCP, navigate to the services tab and turn on DHCP. Once this is done, we need to focus on editing pools so our DHCP server knows how to assign IP addresses. serverPool is the default pool, and you cannot delete it, so you must utilize this pool. When editing or creating pools, ensure that you have the proper pool name of the pool you want to edit. The fields of entry are pretty standard, just make sure you have the correct gateway and your starting IP address/available IPs are actually available.

Configuring DHCP Relay

• Your VLANs in packet tracer need to know how to find your DHCP server, which you can tell them on the command line of your router. Access the interface you want on your router with interface vlan 100 and then use this command to set the helper IP address of your DHCP server:

• ip helper-address DHCP_SERVER_IP
