# Basic Operation

- Each route connects two TIBCO Enterprise Message Service servers.
- Each route forwards messages between corresponding destinations (that is, global topics with the same name, or explicitly routed queues) on its two servers.
- Routes are bidirectional; that is, each server in the pair forwards messages along the route to the other server.

For example, the compact view at the top of the following image denotes a route between two servers, A and B. The exploded view beneath it illustrates the behavior of the route. Each server has a global topic named T1, and a routed queue Q1; these destinations correspond, so the route forwards messages between them. In addition, server A has a global topic T2, which does not correspond to any topic on server B. The route does not forward messages from T2.
