Abstract:
In one embodiment, a link utilization threshold is assigned to a first link. Link utilization of the first link and of one or more second links is monitored. The first link is considered to be out-of-policy (OOP) in the event that the link utilization of the first link surpasses the link utilization threshold. In response to the first link being considered OOP, action is taken. An excess utilization of the first link is determined. One or more prefixes currently routed over the first link whose collective per prefix utilization exceeds the excess utilization are determined. Provided that the collective per prefix utilization of the one or more prefixes currently routed over the first link, if added to the link utilization of the one or more second links, would not cause the one or more second links to be considered OOP, the one or more prefixes are redirected over them.
