The following figure illustrates how an update message is routed from a non-gateway server to a remote location.

Canvas 1 Layer 1 Identity Data Store 1 North Replication Server 1 From Replica 1 To Replication Server 2 1 Identity Data Store 2 North WAN Gateway Replication Server 2 From Replication Server 1 To Replica 2 Replica 2 3 To Replication Server 3 2 Identity Data Store 3 South WAN Gateway Replication Server 3 From Replication Server 2 To Replica 3 Replica 3 4 Replication Internal Routing Replica 1

Processing steps

  1. Update received at Identity Data Store 1 at the north location is sent to the embedded Replication Server.
  2. Replication Server 1 routes message to the WAN Gateway only.
  3. The WAN Gateway at the North location (Identity Data Store 2) routes message to Replica 2 and to the WAN Gateway at the south location.
  4. Replication Server 3, which is the WAN Gateway at the south location, routes the message to Replica 3.
