Lesson 6 Creating and configuring site links
Objective Create and configure site links.

Creating Configuring Site Links

After you configure the sites for your network, you create site links in Active Directory to map the connections between the sites.

Question - Answer

Question: What does a site link do?
Answer: They enable the domain controllers in different sites to replicate the Active Directory database information to one another.

How to create a site link (Steps)

To create a site link:
  1. Open Active Directory Sites and Services from the Administrative Tools menu.
  2. Expand Sites, and then expand Inter-Site Transports.
  3. Right-click IP or SMTP, depending on which protocol you want the site link to use. Then click New Site Link.
  4. In the Name box, type the name for the site link.
  5. Click two or more sites to include in this site link, click Add. Then click OK.
  6. The FlipBook below will walk you through this process in detail.

Cost, replication intervals, and schedules

Cost, replication interval, and schedule are properties of the site link.

Cost

The cost of a site link refers to the relative efficiency of using that link for replication. Setting a low cost on a link that uses a high bandwidth connection and a higher cost on a link that uses a slow connection will ensure that the faster connection is used when a domain controller replicates its Active Directory information.

Replication

Replication interval refers to the period of time that goes by between replications. Schedule: refers to the days of the week and/or times of day that replication can occur. All of these can be configured by the administrator, thus allowing you to control the replication topology and link availability.
Note: Note that when you create the site link, these properties are set to the default values (cost of 100, replication interval of 3 hours, and all periods of time on the schedule available for replication).
How to configure site links
To configure site links, you begin by repeating the steps for creating a site link enumerated above. Once you have decided which protocol you want your site to use, you :
  1. Right-click the site link, and then click Properties.
  2. On the General tab of the Properties dialog box, change the values for cost, replication interval, and schedule as needed, and then click OK.

In the next lesson, you willl learn how to create bridges between your site links.
