The syntax for the drop route command is:
drop route to dest_replication_server [with nowait]
The with nowait option instructs Replication Server to close the route even if it is unable to communicate with the destination Replication Server.
WARNING! Use the with nowait clause only if you do not intend to ever use the destination Replication Server, or if you must drop the route from the source Replication Server while the destination Replication Server is unavailable, or if you are attempting to add or change login names and passwords for direct routes. Avoid using the with nowait clause whenever possible.
After you use drop route with the with nowait clause, use the sysadmin purge_route_at_replicate command to remove all references to a primary Replication Server from the Replication Server at the replicate site.
