During network construction, its planning is particularly important. For the configuration of cisco 2600 dhcp, we have made a simple design here. If there is no document to plan the DHCP you want to do. Even if it is just a piece of paper, it is recommended that you plan it first, or there will be problems when configuring it later. Although I can find a lot of DHCP on the Internet, it is much more detailed
