Overview of RIB

Each routing protocol selects its own set of best routes and installs those routes and their attributes in
RIB. RIB stores these routes and selects the best ones from among all routing protocols. Those routes
are downloaded to the line cards for use in forwarding packets. The acronym RIB is used both to refer
to RIB processes and the collection of route data contained within RIB.
