What is intrasite and intersite replication topology?

Hi, The difference between these two replication topologies can be summarised below: Intra-site replication refers to replication between domain controllers in the same site whereas Inter-site replication refers to replication between DCs belonging to different sites.

What is Intrasite in Active Directory?

Intrasite and Intersite replication. In intrasite replication, all the domain controllers inside the same site will replicate each other. In Intersite replication, Selected Domain controllers of two different sites will replicate during specified interval.

What is an Intersite?

The intersite topology generator is an Active Directory process that defines the replication between sites on a network. It runs the KCC to determine the replication topology and resultant connection objects that the bridgehead servers can use to communicate with bridgehead servers of other sites.

What type of replication does Active Directory use?

There are two basic types of replication in a Windows 2000/Windows Server 2003 environment: Intra-site replication occurs between domain controllers within a site. Inter-site replication occurs between domain controllers in different sites.

What is bridgehead server in AD?

A bridgehead server is a domain controller (DC) that functions as the primary route of Active Directory (AD) replication data moving into and out of sites. Therefore, if you have DCs from multiple domains in each of your sites, you’ll need multiple bridgehead servers to transport each domain’s replication traffic.

Is AD replication pull or push?

Active Directory replication is a one-way pull replication whereby the DC that needs updates (the target DC) gets in touch with the replication partner (the source DC). Components of the replication topology such as the KCC, connection objects, site links, and site link bridges are to be checked by the administrator.

What is repadmin?

Repadmin is a cmd application for diagnosing AD replication issues. Via Repadmin it is easy to view replication topology for every domain controller. And use this knowledge to manually change it and initiate replication communications between controllers.

What is Intersite replication?

Intrasite replication occurs between DCs within a site. The KCC automatically creates replication connections between DCs within the site. The ring topology created by the KCC defines the path through which changes flow within the site. All the changes follow the ring until every DC receives them.

How long does it take for Active Directory replication?

Active Directory replication is based on the theory of ‘multi-master loose consistency with convergence’. Intra-site replication on Win2003 DC’s will only take fifteen seconds, but by default inter-site replication is 180 minutes (three hours).

What is Active Directory replication topology?

Replication Topology in Active Directory. Replication Topology is the route by which replication data travels throughout a network. Replication occurs between two domain controllers at a time. Over time, replication synchronizes information in Active Directory for an entire forest of domain controllers.

Replication between two sites is known as Intersite Replication. Since bandwidth two different sites is usually very limited, so intersite replication is used to manage and control replication traffic where as Intra-site replication refers to replication between domain controllers in the same site.

What is domain controller replication?

Domain Controller and Replication Management Functions. The domain controller (DC) and replication management functions provide tools for finding data about a DC, converting the names of network objects between different formats, manipulating service principal names (SPNs) and directory service agents (DSAs), and managing replication of servers.
