Right -- I had focused only on 8/16/24.
If you were to try this with a distribute-list, would this work as well?
router bgp 11
<snip>
neighbor 11.1.1.8 distribute-list 100 in
access-list 100 permit ip 0.0.0.0 127.255.255.255 host 255.0.0.0
access-list 100 permit ip 128.0.0.0 63.255.255.255 host 255.255.0.0
access-list 100 permit ip 192.0.0.0 63.255.255.255 host 255.255.255.0
access-list 100 permit ip host 0.0.0.0 host 0.0.0.0

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
