Global Destinations
Routes forward messages only between global destinations—that is, for topics the
global
property must be set on both servers (for queues, see
Routed Queues).
For more information about destination properties, See Destination Properties.
The following image illustrates a route between two servers, C and D, with corresponding destinations T1 and T2. Notice that T1 is global on both C and D, so both servers forward messages across the route to the corresponding destination. However, T2 is not global on C, neither C nor D forward T2 messages to one another.
