Slot/Internal Cache
The router operating system maintains an “internal” cache storage space on (and
for) each slot in the router. This slot-level, internal cache stores routing
information captured from traffic originated on the router. For example, the PING
protocol, the IP protocols, and TFTP can each generate their own traffic destined
for IP address locations internal or external to the router.
The internal cache provides to such protocols a local, high-speed database of best
routes from that slot to any other IP destination address in your network.
If the protocol application cannot find in the internal cache a route to the desired
destination, then it searches the main routing table to find one. Once the
application finds a route in the main routing table, it adds that route to the internal
cache for the local slot.
If the routing table changes (with old routes replaced by new routes), the changes
also propagate to the internal cache on the same slot.
The internal cache is limited and fixed in size, and operates on a first-in, first-out
(FIFO) basis. For this reason, cache entries (routes) also have a finite lifetime
determined by the size (depth) of the internal cache. (The larger the size of the
internal cache, the longer it takes for an entry in that cache to disappear.)
With the
ip command, you can examine
• The entire contents of the internal cache on any slot
• A subset of the total contents of the cache on any slot
To view the internal cache on any slot, enter the
ip command using the following
syntax:
ip cache 255.255.255.255 -
<s>
-
<
s
>
is a slot number.
255.255.255.255 is the default address bit mask for the internal cache on any slot.
