As shown in the following figure, Switch C and Switch D are access devices for the users in VLAN 10 and VLAN 20
respectively. Switch B is a gateway, and Switch A a core device. The requirements are listed as follows:
Switch A works as a DHCP server to assign IP addresses of different network segments dynamically to users in different
VLANs.
Users in VLAN 10 and VLAN 20 obtain IP addresses dynamically.
