Default: 60 minutes
Options: 1 through 65,535 minutes
Function: Sets the amount of time, in minutes, between changes in the value of the Master
Encryption Key.
Instructions: Accept the default, or select another value within the specified range. The value
for this parameter must be the same on both sides of a link.
If the router clocks are not synchronized and you want to use encryption, set this
parameter to a value large enough to compensate for the time difference
between the routers. This ensures that the MEKs are the same on both sides of a
link.
