As shown in 

, DHCP clients reside on network 10.10.1.0/24. The IP address of the DHCP 

server is 10.1.1.1/24. Because the DHCP clients reside on a different network with the DHCP server, a 

DHCP relay agent is deployed to forward messages between DHCP clients and the DHCP server. 

VLAN-interface 1 on the DHCP relay agent (Switch A) connects to the network where DHCP clients 

reside. The IP address of VLAN-interface 1 is 10.10.1.1/24 and the IP address of VLAN-interface 2 is 

10.1.1.2/24.

After the preceding configuration is complete, DHCP clients can obtain IP addresses and other network 

parameters through the DHCP relay agent from the DHCP server. You can use the display dhcp relay
