Use the soft-preemption cleanup-timer command to set the amount of time that the point of preemption must wait to receive the Path tear notification from the ingress LSR, before sending a hard preemption path error.
device# configure
device(config)# router mpls
device(config-router-mpls)# policy
device(config-router-mpls-policy)# soft-preemption cleanup-timer 30
The following example shows setting the soft-preemption timer to 30.
device# configure device(config)# router mpls device(config-router-mpls)# policy device(config-router-mpls-policy)# soft-preemption cleanup-timer 30
