This read-create value, in hundredths of a second, approximates the period from when a route change occurs to when a resulting RSVP message actually appears on this interface. It reflects the expected reaction latency of RSVP signaling to underlying routing changes, which helps other network elements gauge how quickly RSVP state should be expected to update after a reroute. An administrator tuning fast-reroute-sensitive RSVP-TE deployments might reduce csRsvpIfRouteDelay to reflect a faster-converging IGP on this interface.
