Since you say FIB, yes. If all RIB prefixes and their sub-prefixes go =
the same next-hop, then you don't need to install additional entries in =
the FIB. Some platforms only can install ~8k/second. Reducing =
duplicate entries is always helpful.
One can't do RIB compression due to the nature of the protocol.
