"...To permit only supernet 10.10.0.0/19, we use an extended access list,
such as access-list 101 permit ip 10.10.0.0 0.0.0.0 255.255.224.0 0.0.0.0.
The format of the extended access-list command is as follows:
access-list <access-list-number> {deny|permit}

Hi Group,
How can the following extended access-list only allow 172.0.0.0 networks
with masks between 18 and 25 bits? Any URLs or related document?
access-list 100 permit ip 172.0.0.0 0.255.255.255 255.255.192.0 0.0.63.128
Thanks.
