Can you configure OSPFv2 without the network command? Today’s post gives you the answers to a recent CLI Lab that lets you practice OSPF interface configuration. Check out the lab, create your answer, and check back here to compare.
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)
The previous sample question gave us lots of example static IPv4 routes to think about. The answer and explanation are below the fold, as usual. Ask’em if you’ve got’em!
This week’s sample question is about static IPv4 routes. The question makes you think not only about syntax, but also about the meaning of the parameters of the ip route command. The wording is a bit tricky because I’ve attempted
This latest lab lets you exercise your basic EIGRP config skills, with a few twists. Does the actual link speed matter? Do you recall how to use wildcard masks in your EIGRP config? And how do you use multiple unequal-metric
#EIGRP uses a complex metric calculation. Most of us do not memorize the math formula, instead remembering the metric components: slowest bandwidth in the route and cumulative delay for all links. This lab lets you ponder how to configure EIGRP
Host A web browsers to server E, which sits on a different subnet. Who ARPs for whom, and where? Check the question, pick your answer, and come back here to check your answer and see the explanation.
Are you an #ARP pretender? ARP is simple. At the same time, ARP can be used as both a testing tool and interview tool determine whether someone really knows how networks work, or if they just read the basics in
