RSVP updates available bandwidth values without notifying IS-IS

When RSVP label-switched paths (LSPs) and segment routing LSPs coexist on a link, RSVP takes into account how much bandwidth the segment routing LSPs use. By default, RSVP updates the values for the local unreserved bandwidth and the maximum available bandwidth and passes the values on to IS-IS.you can configure RSVP to update available bandwidth values without notifying IS-IS if the bandwidth change is within a certain threshold configured at the [edit protocols rsvp interface interface-name update-threshold-max-reservable]. If you configure the local-bw-override-threshold statement at the [edit protocols rsvp interface interface-name non-rsvp-bandwdith] hierarchy level, RSVP always updates the available bandwidth values. However, it reports only the new values to IS-IS if the bandwidth change passes the threshold.
