On the other hand, if a link is defined as a \b FATPIPE,
each flow going through this link will be provided with the complete bandwidth,
i.e., no sharing occurs and the bandwidth is only limiting each flow individually.
+Please note that this is really on a per-flow basis, not only on a per-host basis!
The complete bandwidth provided by this link in this mode
is ``#flows*bandwidth``, with at most ``bandwidth`` being available per flow.
\note
This tag is <b>only available</b> when the containing AS uses the "Cluster" mode!
-TODO: Is default=shared correct?
+Using this tag, you can designate an already existing link to be a backbone.
Attribute name | Mandatory | Values | Description
