Hi

I read this prefix list.

Can I know why there is "le 24" after network block in /22 and /21

Why don't have "le 24" after /24?

I also saw another prefix list before. They use "le 32" instead of  "le 24"

What are their different?

ip prefix-list prefix-filter-as100 seq 10 permit 202,168.136.0/22 le 24
ip prefix-list prefix-filter-as100 seq 20 permit 202,22.92.0/22 le 24
ip prefix-list prefix-filter-as100 seq 30 permit 202,21.148.0/22 le 24
ip prefix-list prefix-filter-as100 seq 40 permit 203,178.88.0/21 le 24
ip prefix-list prefix-filter-as100 seq 50 permit 178.88.74.0/24

Thank you so much
