DHCP client configuration example

Network requirements

On a LAN, Switch B contacts the DHCP server through VLAN-interface 2 to obtain an IP address, DNS
server address, and static route information, as shown in
on network 10.1.1.0/24. The DNS server address is 20.1.1.1. The next hop of the static route to network
20.1.1.0/24 is 10.1.1.2.
The DHCP server uses Option 121 to assign static route information to DHCP clients. The destination
descriptor field comprises two parts, subnet mask length and destination network address. In this
example, the value of the destination descriptor field takes 18 14 01 01, a hexadecimal number
indicating that the subnet mask length is 24 and destination network address is 20.1.1.0, and the value
of the next hop address field takes 0A 01 01 02, a hexadecimal number indicating that the next hop is
10.1.1.2.
