A dedicated route distributes only transactions for a specific primary connection. You can
create a dedicated route to the replicate Replication Server to replicate high priority
transactions or to maintain a less congested path for a specific primary connection.
Note: You can only create a dedicated
route between two Replication Servers if there is a direct route between the two
Replication Servers. You cannot create a dedicated route if there is only an
indirect route between the Replication Servers.
