I'm having trouble understanding IP Prefix-lists can anybody clarify this
for me?

I have this question; use a prefix list with the minimum amount of lines to
allow 1,2,4,5 networks in.

192.54.1.0/24

192.54.2.0/24

192.54.4.0/24

192.54.5.0/24

192.54.21.0/24

192.54.22.0/24

I have 3 lines, 2 denying 21, and 22, the other allowing everything.

Is this the minimum?, if not why not?

Thanks in advance for your help.

Regards

Lee Donald.
