Explanation
Site Link Bridging: By default, site links are transitive, or "bridged." If site A has a common site link with site B, site B also has a common site link with Site C, and the two site links are bridged, domain controllers in site A can replicate directly with domain controllers in site C under certain conditions, even though there is no site link between site A and site C. In other words, the effect of bridged site links is that replication between sites in the bridge is transitive. The setting that implements automatic site link bridges is Bridge all site links, which is found in Active Directory Sites and Services in the properties of the IP or SMTP intersite transport By default, all site links are transitive. We recommend that you keep transitivity enabled by not changing the default value of Bridge all site links (enabled by default).
