An intermediate Replication Server can accept transactions from one or more Replication Servers. Replication Server, however, does not support routing schemes in which routes diverge from the same source Replication Server, then converge at the same intermediate or destination Replication Server.
For example, in Figure 6-4, only one route from NY_RS to LA_RS can be supported. If the route from NY_RS to LA_RS is supported, then the route between CHI_RS to LA_RS is not supported.
