Branch IP Addressing Deployment Overview
Applies To: Windows Server 2012
The following illustration shows the branch office IP addressing topology when you choose to install a DHCP server and you have two subnets.

Note
You are not required to deploy a DHCP server or more than one subnet; these items, as well as additional servers that you might want to deploy in your branch offices, are included in this image to illustrate the possibilities that are available to you.
Branch Office IP Addressing Components
Following are the components for branch office IP addressing.
Router
This deployment guide provides instructions for deploying a branch office network with two subnets that are separated by a router with DHCP forwarding enabled. You can, however, deploy a Layer 2 switch, a Layer 3 switch, or a hub, depending on your requirements and resources. If you deploy a switch, the switch must be capable of DHCP forwarding or you must place a DHCP server on each subnet. If you deploy a hub, you are deploying a single subnet and do not need DHCP forwarding or a second scope on your DHCP server.
Static TCP/IP configurations
The servers in this deployment are configured with static IPv4 addresses. Client computers are configured by default to receive IP address leases from the DHCP server.
DHCP server BRANCH1-DHCP1
The DHCP server, named DHCP1, is configured with a scope that provides Internet Protocol (IP) address leases to computers on the local subnet. The DHCP server can also be configured with additional scopes to provide IP address leases to computers on other subnets if DHCP forwarding is configured on routers.
Client computers
Client computers running Windows 8, Windows 7, and Windows Vista are configured by default as DHCP clients, which obtain IP addresses and DHCP options automatically from the DHCP server.
