When you connect buses, you need to define the foreign
buses for every bus, and the routing definition between each pair
of connected buses in the network. Where destination defaults are
used, you can configure them to suit your design.
About this task
For a conceptual overview of connecting different service
integration buses, including security issues, refer to
Interconnected buses.
You can configure a bus to connect to, and exchange messages with, other messaging networks. To do this, you must configure a foreign bus definition. A foreign bus definition encapsulates information related to the remote messaging network, such as the type of the foreign bus and whether messaging applications are allowed to send messages to the foreign bus. Messages route to a foreign bus either directly through a link between the local bus and the foreign bus, or indirectly through one or more intermediate buses.
