Connect several service integration buses in a network directly
or indirectly by creating foreign bus definitions and routing links between
them. You can also enable point to point or publish subscribe messaging across
multiple buses.
About this task
For a conceptual overview of connecting different service integration
buses, including security issues, refer to
Multiple bus topology.
A foreign bus is a representation of another service integration
bus, or a WebSphere MQ queue manager, with which an existing service integration
bus can exchange messages. Messages are routed 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. Regardless of where the buses exist, if one
is foreign to the other, it requires a foreign bus link.
