This object specifies a relative percentage of unreachable
hosts. The relative unreachable host percentage is based on a
comparison of short-term and long-term measurements. The
short-term measurement reflects the percentage of hosts that
are unreachable within a 5-minute period. The long-term
measurement reflects the percentage of unreachable hosts within
a 60-minute period. The following formula is used to calculate
this value:
Relative percentage of unreachable hosts equals to the
difference between short-term percentage and long-term
percentage divided by long-term percentage.
The master controller measures the difference between these two
values as a percentage. If the percentage exceeds the
user-defined or default value, the exit link is determined to
be out-of-policy.
The value of this object is valid if the corresponding value of
cpfrMapUnreachableType is set to 'relative'.
