I recently started working on the JNCIP Case studies from Harry Reynolds' JNCIP book. I am working with Olives and was going to attempt to do the second case study which is all about interfaces. I thought that this particular lab might be that great to do because of the many interface types and how I only had fxp interfaces to work with. I know that in the book, all labs build on previous labs and was wondering if you guys have found certain labs more useful than others? I will certainly still attempt to do them all, but what do you guys suggest in the way of studying? Do them all and just acccomodate my configs? Skip certain labs that require real devices? Just wanted some expert opinions. Thanks guys.
