Hello,
Task is asking to deny some hosts with the min lines necessary in access
list. It is also asking to to deny traffic from any other host.
Hosts are:
51.3.0.1
51.5.0.1
51.7.0.1
51.3.0.9
51.5.0.9
51.7.0.9
Solution:
======
access-list 1 deny 51.3.0.1 0.0.0.8
access-list 1 deny 51.5.0.1 0.2.0.8
access-list 1 permit any
Question:
======
How to verify that this really didn't block any other hosts ??
I know the login behind this solution " AND the networks to the the network,
XOR t get the mask "
However, I need to hear your feedback about how to make sure that this
didn't really break it up.
I was thinking of the following as a solution
access-list 1 deny 51.3.0.1 0.0.0.8
access-list 1 deny 51.5.0.1 0.0.0.8
access-lisy 1 deny 51.7.0.1 0.0.0.8
access-list 1 permit any
Thanks for your feedback.
Yasser
