Parameter Description
<maxsuppress>
<1-255>
A number that is multiplied by reachtime to give the maximum
time in minutes for which a suppressed route must remain stable
in order to become unsuppressed. The lowest maxsuppress value
of 1 gives a maximum suppression time of 1 x reachtime, and the
highest maxsuppress value of 255 gives a maximum suppression
time of 255 x reachtime.
For example, if reachtime is 15 and maxsuppress is 4, the route is
unsuppressed after 60 minutes of stability even if its FoM still
exceeds reuse. The default is 4.
<unreachtime> <1-45>
The time it takes, in minutes, for the route's instability penalty to
halve if the route remains unstable. The default is 15 minutes.
