size for a router as it will be an indicator of the ability
of the router to function within the given application space,
and whether the router will be able to handle projected
network growth.
As a benchmarking value, it is necessary to discover this
value so that performance measurements can be made up to the
maximum possible forwarding information base size.

5.8 Forwarding Information Base Learning Time
Definition:
The forwarding information base learning time is the time
taken for a router to receive and process received routing
messages, and to construct (and, possibly to distribute
amongst the interface cards in the router) the forwarding
information base.
Discussion:
It takes time for a router to construct its forwarding
information base. A router needs to process received routing
packets, build the routing information database, select the
best paths, build the forwarding information base and then
possibly distribute the forwarding information base or a
subset thereof to the interface cards. This entire process
can take several minutes with very large forwarding
information bases.
Terminology for FIB based Router Performance July, 2000
When performing benchmarking tests that take the forwarding
information base into account, time must be allocated for the
router to process the routing information and to install the
complete forwarding information base within itself, before
performance measurements are made.

in [3].
When advertising routes into a router to perform benchmarking
tests as a function of the forwarding information base
installed within the router, it is necessary to ensure that a
router does not aggregate routes.
Thus, when routes are advertised to the router or installed
statically, care must be taken to ensure that the router does
not aggregate routes.
For example, if advertising a set of /24 network prefixes
into a particular port on the router, 256 consecutive /24
routes, sharing a common leading 16 bits, should not be
advertised on a single port. If this is done, then the
router will install a single entry within the forwarding
information base indicating that all networks matching a
particular /16 network prefix are accessible through one
particular entry.
Route aggregation on a router can be turned off, but routes
should still be advertised into the router in such a manner
as to avoid route aggregation.
