If you maximally disaggregate to /24, you end up with about 12M fib entries. At /25 this doubles and you double it again for every bit you move right. At /24, we are on borrowed time without walking right. Also, the CPU in most routers won’t handle the churn of a 10M prefix RIB. Owen

Which one is easier,
1. Convincing the tens of thousands of network operators and equipment vendors to modify configs and code to accept more specifics than /24, or
Equipment vendors can already support 10 million entries in FIB. They just ask for a little bit of cash for it.
