In this lab, we worked in Packet Tracer to build a small enterprise network representing a single distribution zone, setting up DHCP, DNS, and HTTP services.

• Setting up auto-backups in Packet Tracer
• Configuring edge, distribution, and core switches
• Setting up an IP helper
• Setting up DNS, DHCP, and HTTP services

• 6x 2960-24TT switches
• 1x 3560-24PS multilayer switch
• 2x Server-PTs
• 6x Copper cross-over cables
• 2x Copper straight-through cables

To start off this lab, I enabled auto-backups in Packet Tracer. To do this I went underneath options and selected preferences. From the preferences window, I went to the miscellaneous tab. From here I set the Auto File Backup Interval to 1 minute:

I then saved my lab so that auto backups would initiate. With this done, I went on to set up a subnet table that I would use for the remainder of the lab.

I set up a subnet table taking note of VLAN Names, VLAN IDs, network addresses, default gateways, host ranges, and DHCP pool ranges for each of the required VLANs for this lab:

With my subnet table complete I could move to actually working within Packet Tracer to build my network

The goal for our lab is to create a single-distribution area. I started by creating three sections: border, core, and edge. I dropped a 3560-24PS multilayer switch in my border section, and named it Hospital Router. I then dropped three 2960-24TT switches naming them North Core, South Core, and Data Center Core. I then attached two Server-PTs to the Data Center Core, naming them DNS Server and DHCP Server. Finally, I used copper-cross-over wires and wired each of the core switches to the Hospital Router, and the edge switches to the respective core switches. Then using copper-straight-through, I connected each of the servers to the Data Center Core. I took a screenshot of this for my second deliverable.

To configure the DHCP Server I started by going to its IP configuration and giving it an IP address of 10.10.0.2, a /24 subnet of 255.255.255.0, and finally a default gateway of 10.10.0.1.

I then went to the 'Services' tab and selected DHCP. I turned DHCP on and added the corresponding DHCP pools for the client VLANs.

Finally, I went to the CLI on the Hospital Router and ran the following commands to set an IP helper address pointing to the DHCP Server:

enable
conf t
ip helper-address 10.10.0.2

Below is the subnet table that I used for the rest of this lab:
