Montiean,

So you really need to be asking yourself, what are you actually filtering
and to what granularity you will need. I would say it is question dependant.

Subject: wildcard mask question

Folks,
  Just want to get the idea on wildcard mask using acl in the lab.
For an example, let say we need to use only one statement in acl to filter
routes below

192.168.20.0/24
192.168.21.0/24
192.168.22.0/24
192.168.23.0/24

So we can use either ways as below

access-list 1 permit 192.168.20.0 0.0.3.0 or access-list 1 permit
192.168.20.0 0.0.3.255

The result is going to be the same but which way should be right in the lab.
Any comments would be appreciate.

Thanks,
Montiean
