Dynamic IP address assignment configuration example
Network requirements
As shown in Figure 25, the DHCP server (Router A) assigns IP addresses to clients on subnet
10.1.1.0/24, which is subnetted into 10.1.1.0/25 and 10.1.1.128/25.
Configure DHCP server on Router A to implement the following assignment scheme.
