Hi,
When you specify ge 23, it would filter all the routes with prefix of 23 and
greater, so should include mask /23, /24,/25.....till/32.

Subject: ip prefix-list ....
Could someone explain to me how is the "ge" and "le" options are used
for in a prefix list statement?
Example:
ip prefix-list TEST permit 172.16.0.0/24
ip prefix-list TEST permit 172.16.1.0/24
ip prefix-list TEST permit 172.16.2.0/24
ip prefix-list TEST permit 172.16.3.0/24
I understand that these 4 prefix-lists together will permit the 4
subnets.
But how is it equal to:
ip prefix-list TEST permit 172.16.0.0/22 ge 23
I know how to get the /22
172.16.00000000.0/24 = 0.0
172.16.00000001.0/24 = 1.0
172.16.00000010.0/24 = 2.0
172.16.00000011.0/24 = 3.0
So the common bits would be /22, but why ge 23? How is it
calculated??
Thanks!
H.
