The Refresh Interval, Retry Interval, and Expire Interval are all 32-bit elapsed times measured in seconds. They express the timing parameters which the cache expects the router to use in deciding when to send subsequent Serial Query or Reset Query PDUs to the cache. See Section 6 for an explanation of the use and the range of allowed values for these parameters.
