5.2 Example for DHCP Interface Relay
5.2.1 Network Requirements
The administrator deploys one DHCP server on the network, and wants the server to assign
IP addresses to the computers in the Marketing department and the R&D department. It

After adding the DHCP server, the network topology will be as shown in Figure 5-5.
The Marketing department and the R&D department belong to VLAN 10 and VLAN 20,
respectively. The IP address of VLAN interface 10 is 192.168.2.1/24, and the IP address of
