Message Networking supports a bridging feature in which Message
Networking is used to transmit messages to or from remote machines
designated as bridged machines. With this feature, Message Networking
no longer acts as a hub for all message activity between remote
machines in the network. Instead, Message Networking only allows
messages to pass between two remote machines when one of the remote
machines is designated as a bridged remote machine. Any attempts
to send messages directly between nonbridged remote machines fail.
This feature supports both the bridge
and hybrid network configurations supported by Message Networking.
If you want to use Message Networking in a hub-and-spoke network
configuration, you cannot use the bridging feature.
The Number of Bridged Nodes parameter on the Customer
Options page determines whether the Message Networking system
is being used in a hub-and-spoke or bridge configuration:
- When the Number of Bridged Nodes is set to 500 (the maximum),
the system is being used in a hub-and-spoke configuration. This
parameter is always set to 500 for Message Networking systems
running on the S3400-H server.
- When the Number of Bridged Nodes is set to a number below 500,
this parameter specifies the number of remote machines that can
designated as bridged systems. When bridging is used, a parameter
on the Remote Machine Administration page allows you to designate
a remote machine as a bridged machine. The number of remote machines
you designate as bridged machines cannot exceed the Number of
Bridged Nodes specified on the Customer Options page.
Note: If the number of systems administered
as bridged machines equals the Number of Bridged Nodes on the
Customer Options page, you must not modify
the Number of Bridged Nodes parameter to reduce the number of
bridged nodes. If you do, the system removes the bridging from
the first system you administered as a bridged machine.

Networks for same bridge network configurations.
