How do I set up Active Directory site topology?

1. Create a list of Active Directory sites needed in your organization’s network topology.
2. Define the basic TCP/IP configuration for each site.
3. Design the IP subnets and configure sites that use them.
4. Create the domain controller and assign the relative sites for them.
5. Configure replication that will occur between the domain controllers.
6. Configure applications and services that require special replication.
7. Monitor and measure the effectiveness of the site topology.
