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 [...]

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 [...]

With enough repetition, you should be able to imagine a small network of routers, choose a subnetting plan, choose addresses for the router interfaces, and configure those addresses, all pretty [...]

Repetition helps when learning IP addressing and subnetting. The next lab gives you more reps with subnetting math and with configuring router IP addresses. If you already know the math, make [...]

The next lab combines a little bit of subnetting math with IP address configuration. If you know how to calculate the IP addresses in a subnet and how to configure IP addresses, make this one a [...]

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 [...]

CCNA 200-301 Volume 1 Chapter 16 has several good examples you can recreate in Packet Tracer (PT). This chapter focuses on IPv4 routing, both the concepts and some of the related configuration. [...]

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 [...]

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 [...]
