What about this.

ip prefix-list DEFCLASSFUL seq 1 permit 0.0.0.0/0
ip prefix-list DEFCLASSFUL seq 8 permit 0.0.0.0/1 ge 8 le 8
ip prefix-list DEFCLASSFUL seq 16 permit 128.0.0.0/2 ge 16 le 16
ip prefix-list DEFCLASSFUL seq 24 permit 192.0.0.0/3 ge 24 le 24

Subject: Prefix List Question

Hello,

If used in an inbound route-map via BGP, would the following prefix-list
allow only default and classful routes in from a given neighbor?

ip prefix-list DEFCLASSFUL seq 1 permit 0.0.0.0/0
ip prefix-list DEFCLASSFUL seq 8 permit 0.0.0.0/0 ge 8 le 8
ip prefix-list DEFCLASSFUL seq 16 permit 0.0.0.0/0 ge 16 le 16
ip prefix-list DEFCLASSFUL seq 24 permit 0.0.0.0/0 ge 24 le 24

Thanks
