    Hello, colleagues!

    Whether I understand the theory?

    For example X460 switch.
    FIB - forwarding infromation base = Data Plane = TCAM = ASIC = hardware = 12K IPv4 routes
    RIB - routing information base = Control Plane = CPU = software = 25K IPv4 routes

    Am I right or not?

    Thank you!

    Yes.

    FIB = unique route programmed in the hardware
    RIB = multiple times the same route, from protocols, in memory

    RIB - 25K IPv4 routes for X460 (from RelNotes 15.7)

    Right?
