RE: QS: FIB and RIB: what is the difference

That's making a poor assumption that the device you are speaking about is
hardware based.

More than half of people won't come in contact with those devices (with the

The Routing Information Base is the copy of the routing table stored
in software on the Cisco device.

The Forwarding Information Base is the copy of the routing table
stored in hardware on the Cisco device.

Thanks to Cisco Express Forwarding (CEF) and its use of the FIB,
performance for Cisco routers is much improved.
