hi,seonghui:
i am sure the following statement can give your some hints:
***
The following example configures the secondary line (serial 1) to be activated only when the load of the primary line reaches a certain threshold:
interface serial 0
backup interface serial 1
backup load 75 5
In this case, the secondary line will not be activated when the primary goes down. The secondary line will be activated when the load on the primary line is greater than 75 percent of the bandwidth of the primary line. The secondary line will then be brought down when the aggregate load between the primary and secondary lines fits within 5 percent of the primary bandwidth. ***
good luck!
