DHCP Relay Agent is used for IP address distribution to different locations. An interface configured as a DHCP Relay Agent will retrieve DHCP Broadcasts in its own network environment and send it to the corresponding DHCP server as Unicast.

The device configured in the DHCP Relay Agent can be a Router or a Server. You can also use 3rd party software.

   Step 2

Open the Cisco Router R1 CLI command prompt and configure the GigabitEthernet interfaces on Router.

[code]
R1# conf t
R1(config)# interface gigabitethernet 0/0
R1(config-if)# ip address 192.168.5.1 255.255.255.0
R1(config-if)# no shutdown
R1(config-if)# exit
R1(config)# interface gigabitethernet 0/1
R1(config-if)# ip address 192.168.10.1 255.255.255.0
R1(config-if)# no shutdown
R1(config-if)# exit
[/code]

   Step 3

Configure the DHCP server settings on the Cisco Router. We are configuring the DHCP settings on the router to see the difference on the Relay Agent. We will then try to get the IP address from different locations by canceling the DHCP pool.

[code]
R1# conf t
R1(config)# ip dhcp pool LAN
R1(dhcp-config)# network 192.168.5.0 255.255.255.0
R1(dhcp-config)# default-router 192.168.5.1
R1(dhcp-config)# dns-server 192.168.5.1
[/code]

   Step 5

Select PC1 IP address configuration as DHCP.

   Step 10

Remove the DHCP pool on the Cisco Router with the no ip dhcp pool LAN command, and then execute the ip helper-address command on the interface that will perform the DHCP RELAY AGENT function.

[code]
R1# conf t
R1(config)# no ip dhcp pool LAN
R1(config)# interface gigabitethernet0/0
R1(config-if)# ip helper-address 192.168.10.10
[/code]

   Step 13

As shown in the following image, the PC1 IP address settings are obtained from the DHCP Server with IP address 192.168.10.10. You can also see that PC1 gets the first IP address from 192.168.5.150 – 192.168.5.200 IP address range…
