Hi, anyone whom see this article.
Can you explain to me what is the meaning for below prefix-list?
ip prefix-list mgmt seq 5 permit 10.1.1.0/24 le 32
if we doesn't state 'ge xx', and then it would be considered as 'ge 0', correct?. if so, above sentence is meaning 10.0.0.0 ~ 10.255.255.255?

Match any subnet starting with 10.1.1.0 (/24 - all 24 bits must match) and with a prefix length of /32 or less. Meaning any network from the /24 of 10.1.1.0 and any subnet of that network down to host routes (/32).
I don't believe your second statement is correct. The least specific it can be is /24 since that is the original "match".
Hope this helps,
Ed

Hello,
In addition to friends' answers here, I've tried to explain prefix lists in depth here:
