Non-gateway replication servers forward update messages from replicas to co-located replication servers only. It is the responsibility of the WAN gateway server to forward these messages to WAN gateway servers at other locations.
The following figure illustrates how an update message is routed from a non-gateway server to a remote location.
- Update received at Identity Data Store 1 at the north location is sent to the embedded Replication Server.
- Replication Server 1 routes message to the WAN Gateway only.
- 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.
- Replication Server 3, which is the WAN Gateway at the south location, routes the message to Replica 3.
