Hey all, I figured I'd share this with others since I found it very useful as I'm studying for my CCNA as well. I know many use Wendell Odom's Official Cert Guide book to study with but did you know he also has a Youtube course as well?
I personally do not have the books but I am using Jeremy's IT Lab, Todd Lammle's CCNA Cert Guide book and have added Wendell's Youtube course into it as well. Personally I love the way he goes over each topic thoroughly and gives great content, which helps to reinforce everything I learned and jotted down from JITL.
Anyway here's the link for the series. It seems like it follows the book's chapters, and as I mentioned I don't have the books so I just search for the topics I am going over. For example I'm going over the IPv6 address types and he has different videos for each type and they're explained very well.
Hopefully it comes in handy for you as much as it has been coming in handy for myself!
