DHCP user class configuration example

Network requirements
As shown in
clients and the DHCP server (Router B). Enable Router A to handle Option 82 so that it can add
Option 82 in DHCP requests and then convey them to the DHCP server.
Configure the address allocation scheme as follows:
Assign IP addresses
10.10.1.2 to 10.10.1.10
10.10.1.11 to 10.10.1.26
Router B assigns the DNS server address 10.10.1.20/24 and the gateway address 10.10.1.254/24 to
clients on subnet 10.10.1.0/24.
