When two replicas have a replication agreement between their suffixes, the suffixes form a topology segment. Each topology segment consists of a left node and a right node. The nodes represent the servers joined in the replication agreement.
Topology segments in IdM are always bidirectional. Each segment represents two replication agreements: from server A to server B, and from server B to server A. The data is therefore replicated in both directions.
