Try a little subnetting math for a quick review, and add some IP address configuration – short, sweet, and just one more quick round of practice. Check out the initial requirements in this post, and come back here for the

By the time go for #CCENT with the ICND1 exam, this kind of exercise should be relatively automatic. The goal here is to help you practice, so that it becomes second nature.  Today’s post shows the answers; useful links below,

Practice makes memory. So, time for some practice with IPv4 address configuration on routers. This post is a traditional Config Lab exercise: you start with a network diagram and some planned IPv4 subnets. Your job: do some subletting math and configure

VLSM Design Drill #1

VLSM causes many #CCENT and #CCNA candidates much heartache. Today’s post shows a VLSM design exercise that is useful for exam prep as well as real life. The idea: begin with an existing design that happens to use VLSM. Then

More practice practice practice! This time, you get some basic IP addressing requirements. Your job: calculate the IP addresses to be used by routers and hosts, and create the router configuration for in the interfaces in the network diagram. No guile,

Analyzing Classful Networks and My Dear Aunt Sally

No, I don’t really have an Aunt Sally. Some of you may have recognized the mnemonic device for multiplication and division (My Dear), and for addition and subtraction (Aunt Sally), as taught to so many school kids in the USA.

Switch IP Config

This next lab begins with a switch that has been configured to allow Telnet + SSH, including password protection – except the fact that neither switch yet has an IP address. This lab asks you to add the IP configuration
