This blog post simply lists the answers to the earlier Config VM from a few days ago. As with all the Config Museum pieces, the goal is to give you a straightforward set of lab requirements: no guile, no tricks, just a chance to exercise. This exercise focuses on configuring IP addresses on Frame Relay interfaces, assuming the interface and subinterface configuration already exists.

This blog post can be a stand-alone lab, but it is also a continuation of an earlier museum piece. The earlier lab asked you to configure Frame Relay, without the IP addressing. This lab adds the IP Addressing details to the picture. So, this lab’s starting point is the previous lab’s ending point.
As usual with these Config Museum pieces, it’s a lab, no guile, no tricks, but just a straightforward chance to practice. Enjoy!

This blog post simply lists the answers to the earlier Config VM from a few days ago. As with all the Config Museum pieces, the goal is to give you a straightforward set of lab requirements: no guile, no tricks, just a chance to exercise. This exercise focuses on Frame Relay, point-to-point subinterface configuration, purposefully leaving out the IP addresses. Some related links:

This blog post is the first of a couple of related Config Museum pieces. As with all Config Museum pieces, this post plainly states some requirements that lead you to then create a configuration. The matching answers post will then list the configuration. Today’s post shows a figure of a Frame Relay design, using global Frame Relay addressing, and asks you to configure the Frame Relay part, ignoring IP addressing. (I’ll likely add the IP addressing for the next Config Museum piece.)
Also note that this is the first post in the CCNA Skills blog since I migrated to a self-hosted wordpress site. So, if you see any formatting weirdness here or on any of the earlier posts, feel free to post, and I’ll look at it. Thanks!

I got started on this discussion of the previous post’s sample question based on a question from a reader of the ICND2 Cert Guide. For the discussion of the answers, I’d like to focus on the one answer that makes you think about both layer 2 and layer 3 forwarding to answer the question: Answer E. For today’s post, I’ll discuss some of the reasoning around that one answer, and I’ll hide the letter answers to the question somewhere near the end of the explanation so to avoid spoiling the answer if you’ve not yet gotten to read the question.

Today’s post is a question that comes with the ICND2 Official Cert Guide. A reader had sent in an errata email, claiming the question was wrong (it wasn’t in this case), but this question is packed with tons of learning points. I thought it’d be a good one to review here in the blog. I’ll post the question today, and work through a couple of the answers in the coming posts.

Today’s post completes the answers to the OSPF lab by listing answers to Part 4. This part looks at the OSPF Router ID concept, and how to configure it. It’s a pretty basic conclusion to the lab, but like most of this stuff, it helps to get in some reps, so the lab spells out some requirements that make you try different ways to set the Router ID on the four routers in the lab.

Today’s post looks at Part 3 of the answers to the OSPF lab recently posted in this blog, with the topic of OSPF. The lab shows how to break down the components that affect the metric for an intra-area OSPF router, as well as showing how to change the OSPF cost components both directly and also indirectly by changing the bandwidth settings. The lab shows three separate routes to give a little variety.

Pearson Education, publishers of the Cisco Press products, hosted me for a CCNA-level OSPF web cast back in February 2012. (You can go here to watch the video of the webcast.) Anyway, during the webcast, anyone watching could send in a question, and there was a set time for me to answer. I answered some of those in the webcast, but not all. The folks at Pearson sent me the list of questions, so I figured it was potentially helpful to list the answers in a blog post. So… here it is!
Some of these may not make sense without watching the video of the webcast, but some will. Also, here’s a link to a PDF that shows the network topology and area designs used in the webcast. (Also, i’ll wrap up the OSPF lab answers here in the next week or so.)

Today’s post looks at Part 2 of the answers to the OSPF lab recently posted in this blog. Part 2 looks at OSPF authentication. In this case, one router (R1) needs to use all three types of OSPF authentication: none, simple password, and MD5. The other three routers each use only one type of OSPF authentication. With the requirements stated in the original lab, that leads to slightly different config on all four routers, which gives you a better chance to experiment. Quick links below:
