Extended IPv4 ACLs? No problem. Matching packets going towards the client? A little more of a problem. Deciding whether you need to match ARP and OSPF in your ACL? Even more of a problem. This latest drill makes you think
This next Extended IPv4 ACL Drill continues to focus on some key ACL concepts. You have to think about where the ACL will reside, and for what direction of packet flow, before choosing the syntax of the commands. This next
The previous post listed a set of ACL requirements that require an IPv4 Extended ACL. Your job: using those requirements, configure an extended named ACL. Of course, this post makes no sense without the post that states the requirements, so check
Extended Access Control Lists (ACLs) can be a challenge for many reasons. In the first few posts in this series, these ACL exercises will focus on just a few of those issues. In particular: The concept and syntax to match
This latest lab breaks the config lab mold just a tad, but for a good reason. It looks like a straightforward config lab, requiring just 10 minutes or so to do on paper. But it sets you up for one
Are you comfortable matching packets with extended IPv6 ACLs? How about with TCP and UDP ports in those ACLs? Here’s a 10-minute lab exercise to practice; all you need is the time and a piece of paper or a place
The previous lab exercise requires you to configure a standard IPv6 ACL. The address range matching should be pretty straightforward. You also need to choose where to put the ACL, and for which direction of flow for the packets. As
IPv6 ACLs – new to #CCNA with the 2016 exam revisions – include both standard and extended ACLs. However, IPv6 standard and extended ACLs have only subtle configuration differences. This lab helps you notice those differences with a lab that
This post makes no sense without the questions from the previous post, so check those out if you’ve not done so already. The questions list ACLs that were typed in a text editor, so they could list an IP address
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)
