Network requirements
• As shown in
693H
Figure 17 , the DHCP server (Switch A) assigns IP addresses to clients in subnet
10.1.1.0/24, which is subnetted into 10.1.1.0/25 and 10.1.1.128/25.
• The IP addresses of VLAN-interfaces 10 and 20 on Switch A are 10.1.1.1/25 and 10.1.1.129/25.
• In address pool 10.1.1.0/25, configure the address lease duration as ten days and twelve hours,
domain name suffix aabbcc.com, DNS server address 10.1.1.2/25, gateway 10.1.1.126/25, and
WINS server 10.1.1.4/25.
• In address pool 10.1.1.128/25, configure the address lease duration as five days, domain name
suffix aabbcc.com, DNS server address 10.1.1.2/25, and gateway address 10.1.1.254/25, and
there is no WINS server address.
