That's why you should not rely on the information in some training 
manuscripts from several months ago. Make an internal wiki, and
write down anything that is important on that wiki. Then when you
are troubleshooting, you can use a search tool to help you find the
relevant info. Because it is your wiki, and you intend for it to
be a support resource, when you implement OSPFv3, you will add
notes to the wiki as you go, noting what you did differently and
