Chapter 3  DHCP Relay Configuration 

3.1  Introduction to DHCP Relay 

3.1.1  Usage of DHCP Relay 

Since the packets are broadcasted in the process of obtaining IP addresses, DHCP is 

only applicable to the situation that DHCP clients and DHCP servers are in the same 

network segment, that is, you need to deploy at least one DHCP server for each 

network segment, which is far from economical. 

DHCP Relay is designed to address this problem. It enables DHCP clients in a subnet 

to communicate with the DHCP server in another subnet so that the DHCP clients can 

obtain IP addresses. In this case, the DHCP clients in multiple networks can use the 

same DHCP server, which can decrease your cost and provide a centralized 

administration. 

3.1.2  DHCP Relay Fundamentals 

Figure 3-1 illustrates a typical DHCP relay application.

Figure 3-1 

Typical DHCP relay application 

DHCP relays can transparently transmit broadcast packets on DHCP clients or servers 

to the DHCP servers or clients in other network segments.   

In the process of dynamic IP address assignment through the DHCP relay, the DHCP 

client and DHCP server interoperate with each other in a similar way as they do 

without the DHCP relay. The following sections only describe the forwarding process 

of the DHCP relay. For the interaction process of the packets, see 1.2.2  Obtaining IP 

Addresses Dynamically.  

1) 

The DHCP client broadcasts the DHCP-DISCOVER packet.
