DHCP Relay Agent Configuration Example

Network requirements
As shown in Figure
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.
