For all the stub networks out there we should be able to aggressively filter routes without much harm.
Stub networks, which, by definition, do not have transit traffic over them, can not filter routes for transit traffic at all. But, if both of two stub networks with address ranges of 131.112.32.0/24 and 131.112.33.0/24 advertise 131.112.32.0/23, the result will be disastrous for the networks. As such, even stub networks should advertise exact address ranges of them. Masataka Ohta
