The default value is infinite.        preferredlifetime - Lifetime over which the route is preferred.                            The default is equal to the valid lifetime.        store             - One of the following values:                            active: Change only lasts until next boot.                            persistent: Change is persistent (default).  Remarks: Adds a route for a given prefix.  Time values can be expressed          in days, hours, minutes, and seconds; e.g. 1d2h3m4s.           When publish is set to no or age, the route will be deleted          after the end of the valid lifetime.  When publish is set to          age, the Route Advertisement will contain the valid lifetime          remaining until deletion.           When publish is set to yes, the route will never be deleted,          regardless of the validlifetime value, and every Route          Advertisement will contain the (same) specified valid lifetime.
