Description
Configure a threshold in bits per second. When SPRING bandwidth utilization exceeds this threshold, Resource Reservation Protocol (RSVP) reports this event to IGP and preempts the labeled switched paths (LSPs). If this threshold is not exceeded, RSVP does not make any changes to the bandwidth allocation.
However, if the local-bw-override-threshold statement is configured
along with the update-threshold-max-reservable statement, RSVP
modifies local unreserved bandwidths even if the threshold is not exceeded. This
change does not report the new maximum reservable bandwidth and local unreserved
bandwidth to IGP until the threshold configuration crosses.
Note that the changes are not applied by modifying the subscription
percentage at the [edit protocols rsvp
interface interface-name] hierarchy level.
Default
The default value is 0.
Options
| update-threshold-max-reservable | Specify a threshold value for maximum SPRING bandwidth utilization in bits per second.
|
| percent percent | Specify a bandwidth utilization change threshold in percentage beyond which RSVP triggers IGP updates. When the change in bandwidth utilization from previously advertised value is more than the percentage configured, RSVP informs IGP about the max reservable bandwidth change. |
