Forwarding Information Base (FIB) Table
The FIB is a table that contains a mirror image of the forwarding information in the IP rout-
ing table. When routing or topology changes occur in the network the route processor up-
dates the IP routing table and the information updates the FIB. Because there is a one-to-
one correlation between FIB entries and routing table entries, the FIB contains all known
routes and eliminates the need for route cache maintenance that is associated with
switching paths, such as fast switching and optimum switching. FIB is used for making IP
destination prefix-based switching decisions and maintaining next-hop address infor-
mation based on the information in the IP routing table.
The forwarding information base (FIB) table contains information that the forwarding pro-
cessors require to make IP forwarding decisions.
The forwarding information base (FIB) is the group of the information to forward traffic in
Layer 3, which is created from Routing Information Base (RIB) on the CPU. You can veri-
fy the forwarding entries in the FIB table with the
show ip route fib
command. To specify
the time to retain the forwarding entries information in the FIB table, use the following
command.
Command
Mode
Description
fib retain forever
Global
Retains the forwarding entries in the FIB constantly.
fib retain time
<1-65535>
Retains the forwarding entries in the FIB for specific
seconds:
1-65535: time value in second
To delete the specified time for retaining the forwarding entries information, use the fol-
lowing command.
Command
Mode
Description
no fib retain forever
Global
Deletes the specified time to retain the forwarding en-
tries in the FIB.
