200-301 V1 Ch17: Router Addresses and Routes

This blog post begins with a router triangle, IP addresses, and working interfaces. All routers can ping their own IP addresses, but the routers only know their own connected routes. You job: Add [...]

The first time you learn about IP routing, some of the basic ideas just do not click until you think hard about the contents of the IP routing table. One of the best tools to make you think about [...]

One of the best ways to learn IPv4 routing is to think hard about IPv4 static routes. Today’s lab gives you more of that with a typical config lab. It starts with a topology and with IPv4 [...]

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 [...]

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 [...]
