Wendell's CCNA Skills Blog

Today’s post kicks off a new CCNA and ICND2 lab. This lab focuses first of VLAN topics, and then STP in some later posts. And instead of starting with a set of requirements and asking you to configure the network, we’ll start this one with a diagram and a chance to think about how to [...]

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 [...]

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 [...]

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 [...]

Today’s post looks at Part 1 of the answers to the OSPF lab recently posted in this blog. Part 1 looks at the IP address config as well as how to configure OSPF to match the listed requirements. The lab makes more sense if you look at the original lab post first! Quick links below: [...]

Today’s post kicks off a new CCNA-level lab on OSPF, in conjunction with a webinar I’m doing with Cisco Press on February 15th. The short version: today’s post lists the lab problem statement. Upcoming posts will list the answers, comments about the lab, and give us a place to discuss that particular part of the [...]

Today’s post wraps up the posts about this lab. Today, rather than leave you with the answers to another chunk of the lab, with some explanations, instead we’ll turn it around into both a troubleshooting and a configuration exercise. First, did the config I supplied for router R4, in the previous post, really work? And [...]

Part 3 of this lab asks you to configure OSPF. For today’s post, I’ll focus on all the OSPF config requested in part 3 of this lab, except for the metric tuning, which I’ll defer for a final post for this lab. But there’s plenty to discuss today. The lab gives us the area design [...]

Part 2 of this lab examines how to configure Frame Relay. Per the lab’s listed requirements, you can take as many defaults as you like, so the config avoids such issues as LMI types, DLCI mapping, and encapsulation. But it does include the basics, along with the creation of point-to-point subinterfaces. And the biggest learning [...]

Today’s post begins the discussion of some answers to the lab mentioned in the title. This post makes little sense without reading the lab post first! Take a look there, and take a crack at doing the lab, at least on paper, before reading below the fold here. Today, I’ll look at Part 1 in [...]
