In this lab, I continued building from Lab 03-2, this time enabling DHCP and setting up IP helper addresses so that all PCs on the network could receive IP addresses through DHCP.

• Configuring a DHCP server with pools
• Setting IP helper addresses
• Setting PCs to receive IPs through DHCP

• Hardware from Labs 02-1 and 03-2
• 1x Copper Straight-Through Cables
• 1x PC-PT

To start, I began by going to my DHCP-01 server. Here I clicked on the services tab and underneath DHCP, I turned DHCP on. I then added a pool for each of my VLANs, setting the default gateway, an address, and the maximum number of users. I used the default server pool for my management VLAN. I made sure to make use of the IP table so that I could properly allocate addresses, subnet masks, and hosts.

With DHCP configured, I added a PC to East-Core-Switch, wiring it to the interface FastEthernet0/3. I then double-clicked this PC and then set it to retrieve its IP through DHCP.

I next needed to allow other PCs on the network to retrieve an IP through DHCP, by setting up IP helper addresses.

I began by going into the console on my East-Core-Switch. Here I ran the following commands to set up IP helpers to forward DHCP broadcasts to the

# Elevate the console
enable

# enter the configuration terminal
configuration terminal

# Select the VLAN interfaces 100-140, and give it an IP helper address that points towards DHCP-01
int vlan 100
ip helper-address 10.34.100.2


int vlan 110
ip helper-address 10.34.100.2

int vlan 120
ip helper-address 10.34.100.2

int vlan 130
ip helper-address 10.34.100.2

int vlan 140
ip helper-address 10.34.100.2

With my IP helper addresses set up, I should be all good to adjust my PCs to retrieve IPs through DHCP.

I went to each of my PCs, selected desktop, and then IP configuration. Here I set each PC to retrieve an IP through DHCP, which they successfully received.

Finally, I pinged from various PCs on my network to ensure that they were still able to communicate.

My submission can be found at this link here. The packet tracer file was the only deliverable required for this lab.
