I’ve been working on my CCNA and have a need to break down the concepts, configurations etc. into bite sized study topics. So instead of creating this one in my notebook as I usually do, I decided I would share some key points of the OSPF protocol. Don’t expect anything ground breaking here, but if you are also working on your CCNA or just want to review, then maybe you’ll also find this handy. Oh and all of these are notes from the CCNA ICND2 official exam certification guide (second edition) by Wendell Odom.
