Wendell's CCENT Skills Blog

This kind of post is meant to be straightforward, but I did add one sort-of sneaky requirement into the list. Why is it sneaky? Well, it’s really more of an ICND2 topic than ICND1, and I try and keep those over in the CCNA Skills blog. Today’s post shows the answers to the lab problem [...]

This blog post sets up a short RIP-2 config exercise. It begins with a router triangle, IP addresses, and working interfaces – essentially the same starting state as the static routes exercise posted recently. All routers can ping their own IP addresses, but the routers only know their own connected routes. You job: Add RIP-2 [...]

Today we’ll move on to the 2nd major task for this lab. As with Task 1, we’ll start with a look at the connected routes, and then chase a few subnets around the topology to find out if the routers appear to be missing any network, auto-summary, and passive-interface commands.

This is post 5I’ll list links to the first four posts after the fold. Today’s post: I’ll wrap up the analysis of task 1, specifically chasing many of the route advertisements so reverse engineer whether the config includes the network, auto-summary, and passive-interface commands.

Post 1 and Post 2 in this lab essentially set us up for today’s post. Today’s post gives you three big tasks, each of which assumes the same topology, IP addresses, and routing protocol (RIP-2) shown in the first two posts. In two of the tasks, your job is to figure out the specific configuration [...]

If you can’t predict what should be in the routing tables when you know the topology and the config (as shown in lab 3 post 1), then you’re not going to be able to predict the config based on the topology and some show command output. Today’s post completes the part of the initial part [...]

Today’s post begins a new CCENT lab, but with a very specific goal: to build troubleshooting skills for the exam. A little later, I may take the time to do a whole post just on the theory behind why I think this style of lab can help you learn some troubleshooting skills. The short version [...]

Today’s post wraps up CCENT Lab 2. I’ll likely extend this lab as lab number 3 as time goes on, because it sets up a nice discussion of auto-summary and maximum-paths. But as promised, today’s post looks at R3’s routing table, again using the configuration as shown in answer part 1, with emphasis on two [...]

Today’s post is really an attempt to get you to think about how RIP-2 works in the context of the lab exercise I started last week. To predict the contents of the IP routing table, you have to think about how routers add connected routes, how RIP advertises those routes, how RIP adds 1 to [...]

Today’s post details a lab exercise. If you have three routers, or use a simulator/emulator, you can build your answer and try it yourself, and see what happens. However, in case you don’t, I’ve set this up so that you can do it as a paper exercise as well. Enjoy!
