The following sections describe the RSVP parameters in more detail.
17.3.2 RSVP Refresh Intervals
As mentioned previously, RSVP soft state management depends upon periodic refreshes of the Path and Resv
messages. RSVP Path and Resv refresh messages are sent periodically to refresh the states in neighbor routers and
ensure that these states do not time out.
In the following formulas, lifetime is how long an RSVP router keeps a path or reservation state as a valid state:
path-lifetime = path-multiplier * path-refresh-interval
resv-lifetime = resv-multiplier * resv-refresh-interval
