The Configure long distance (optional) dialog box displays. If the distance between the merged
fabrics is 10 km or greater, you must configure the connection as a long distance connection.
Selecting a distance invokes an algorithm to compute the required number of BB Credits

credits than the algorithm provides, and it is a good practice to specify a distance that is longer
than the actual distance to be sure enough BB credits are allocated.
