In general, techniques are described for scheduling traffic for delivery over an aggregated bundle of links. The techniques may be implemented by a network device comprising a control unit. The control unit configures a primary logical interface such that the primary logical interface is associated with a primary link of the aggregated bundle of links. The primary logical interface is associated with a primary scheduling module that schedules the traffic for delivery via the primary link. The control unit further, prior to detecting a failure associated with the primary scheduling module, configures a backup logical interface such that the backup logical interface is associated with a backup link of the aggregated bundle links. The backup logical interface is associated with a backup scheduling module that schedules, in response to detecting the failure associated with the primary scheduling module, the traffic for delivery downstream via the backup link.
