I am studying for ccnp tshoot , the book that I am using is ccnp tshoot oficial certification guide . It has alot of problems such as :
1- It does not explain materials , I gotta search in internet for everything that was not in BSCI and BCMSN to get basic knowledge .
2- The most important reason is , I found alot of mistakes up to OSPF AND REDISTRIBUTION CHAPTER such as :
1-It says GLBP stands for global load balancing protocol , not gateway load balancing protocol
2-It says GLBP is not cisco proprietary protocol.
3- It says ospf cost is calculated by deviding 10 ^8 / bandwidth in kbs not in bit/s
So my question is what should I do , Why it is like this , I know all materials up to now but what about those that I do not know . Can I trust on this book ?
Thanks If you help me ?
