It will fail, and software switch many prefixes.

If you're lucky, that is. That's what's supposed to happen, but I have run into this (Sup720non-XL with full feed overflowing the TCAM) and Odd Things happened. Packets that took paths both the routing table and CEF FIB said they shouldn't, stuff like that.

Be afraid, be very afraid...
