A topic space mapping allows subscribers on the local topic space
to receive messages published in the foreign topic space. You can create
topic space mappings between two service integration buses.
Why and when to perform this task
To
map a topic space on a local bus to a topic space on a foreign bus, use the administrative console to complete the following steps.

- In the content pane, select
the bus for which you want to list the foreign buses.
- In the content pane, under Topology, click Foreign
buses. A list of foreign buses is displayed.
- Select the required foreign bus.
- In the content pane, under Additional properties, click Service
integration bus link routing properties. If instead there is a

integration bus.
