ACL Drill Set 3

Today’s post lists several ACL interpretation exercises. Below the fold, you’ll find several ACEs (ACL commands) as typed in a text editor. For each ACL, you must answer two questions:

1) what range of addresses does each ACE match?

2) Will IOS change any of the access-list commands once copied into the config on a router?

Look below the fold for the questions. For more information about how an ACL or ACE might change once copied into configuration mode on a router, check out the launch post for the ACL Drills in this blog.

  1. access-list 1 permit 10.0.0.0 0.0.0.255
  2. access-list 2 permit 10.1.0.0 0.0.255.255
  3. access-list 3 permit 172.16.112.0 0.0.15.255
  4. access-list 4 permit 172.16.113.192 0.0.0.31
  5. access-list 5 permit 172.16.150.0 0.0.7.255
