A route with no intermediate sites is called a direct route. A system with direct routes results in network connections between source and destination Replication Servers.
For example, in Figure 6-1, a seven-site enterprise is shown in a star configuration, with one primary site and six replicate sites. If the replicate site TKO_RS is to submit request functions to the primary site NY_RS, your system would also require a direct route from TKO_RS to NY_RS, in addition to the direct route from NY_RS to TKO_RS.
