Numerical parameter to use when creating a value for the metric in the routing information sent to the destination based on the supplied metric in the routing information received from the source. This field is only used if the redistribution flag is TRUE and the metric conversion field is set to 'constant', 'scale up', 'scale down' or 'truncate'. If the metric conversion field is 'constant' then the new metric value is just the value of the numerical parameter. If the metric conversion field is 'scale up' then the new metric value is the supplied metric multiplied by the value of the numerical parameter (or 0xffffffff if this is smaller). If the metric conversion method is 'scale down' then the new metric value is the supplied metric divided by the value of the numerical parameter (rounded down to the next integer). The numerical parameter cannot be zero in this case. If the metric conversion field is 'truncate' then the new metric value is the lower value of the supplied metric value and the numerical parameter.
