Bit 1 is used to determine whether or not to load share messages across the two link sets. It is
only used when two link sets are specified for the route. When set the MTP3 module will load
share messages for the destination equally across each of the two specified link sets. Otherwise
the MTP3 module will consider the normal link set to be the preferred link set and will only use the
second link set in the event of failure of the normal link set. The bit should be set to 1 to enable
load sharing across the two link sets or zero to disable load sharing and use preferred and
secondary link sets.
All other bits are reserved for future use and must be set to zero.
