Dynamic IP Address Assignment Configuration Example
Network requirements
• As shown in Figure 12 , the DHCP server (Device A) assigns IP address to clients on 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 GigabitEthernet 0/1 and GigabitEthernet 0/2 on Device A are 10.1.1.1/25
and 10.1.1.129/25 respectively.
• Address pool 10.1.1.0/25 has the address lease duration ten days and twelve hours, domain
name suffix aabbcc.com, DNS server address 10.1.1.2/25, WINS server address 10.1.1.4/25,
and gateway address 10.1.1.126/25.
• Address pool 10.1.1.128/25 has the address lease duration five days, domain name suffix
aabbcc.com, DNS server address 10.1.1.2/25, and gateway address 10.1.1.254/25 and has no
WINS server address.
• The domain name suffix and DNS server address in address pools 10.1.1.0/25 and 10.1.1.128/25
are the same. Therefore, the domain name suffix and DNS server address need to be configured
only for subnet 10.1.1.0/24. Subnet 10.1.1.0/25 and 10.1.1.128/25 can inherit the configuration of
subnet 10.1.1.0/24.
NOTE:
In this example, the number of requesting clients connected to GigabitEthernet 0/1 should be less than
122, and that of clients connected to GigabitEthernet 0/2 should be less than 124.
