site bağlantı köprüsü. An Active Directory object that represents a set of site links, all of whose sites
can communicate via some transport. Typically, a site link bridge corresponds to a router (or a set of routers) in an Internet Protocol (IP) network. By default, the Knowledge Consistency Checker (KCC) may form a route through any and all site links in a transitive manner. If this behavior is turned off, each site link represents its own distinct and isolated network. Sets of site links that can be treated as a single route are expressed through a site link bridge. Each bridge represents an isolated communication environment for network traffic.
