• Use the no form of this command to make the router exit the overload state.

• If the time period is not specified, the router remains in the overload state for an infinite period.

• During normal operation, the router may be forced to enter an overload state due to a lack of resources. 

When in the overload state, the router is used only if the destination route is directly reachable by the 
router i.e., it will not be used for other transit traffic.

• This command can be used when the router is overloaded or before executing a shutdown command to 

divert traffic around the router.
