In multi-site deployments, it is strongly recommended to configure the directory servers with location information using the dsconfig create-location command and dsconfig set-global-configuration-prop command. The Directory Server cannot determine LAN boundaries automatically, so incorrect location settings can result in undesired WAN communication. By default, replication also compresses all traffic between directory servers in different locations.

We recommend setting up the locations prior to enabling replication. The dsreplication enable command prompts for location information if you have forgotten to define the property.
