Speak of which, did anyone ever implement FIB compression? I seem to remember the calculations looked really favorable for the leaf node use case (like James') where the router sits at the edge with a small number of more or less equivalent upstream transits. The FIB is the expensive memory. The RIB sits in the cheap part of the hardware.
fib optimize => using LPM table for LEM https://www.arista.com/en/um-eos/eos-section-28-11-ipv4-commands#ww1173031 FIB compression => install only 1 entry into FIB for compressable routes with shared nexthop https://eos.arista.com/eos-4-21-3f/fib-compression/ The feature itself works as intended. version/platform/config compatibility needs some considerations.
