Vincent Bernat has posted a
lengthy description of how the IPv4 routing cache works
and how to tune
it for best results. "Once an entry has been added to the route
cache, there are several ways to remove it. Most entries are removed by the
garbage collector which will scan the route cache and remove invalid and
older entries. It will be triggered when the route cache is full or at
regular interval, once a certain threshold has been met.
