Here's a link I found useful to help me understand these.

Any suggestion of docs to understand ip prefix-list?

I thought I had a good understanding after reading Solies V.II and Cisco pages, but doing a scenario showed that I have some problems. This is one:

ip prefix-list permit 5 10.1.0.0/21 ge 24 le 24

From my understanding, the 21 would be equal wild card mask 0.0.3.255 (of access-lists) and "ge 24 le 24" means that the mask must be 255.255.255.0. The nets 10.1.0.0 to 10.1.7.0 with mask 24 would pass this prefix-list.

Is it correct?
