The Cisco Press BSCN book is great. I highly recommend it. Do all of the labs if you can.
The Cert Guide, on the other hand, is outrageously full of errata. And when I say errata, I don't just mean misprints (althought there are tons of those as well). LSAs and aggregate addresses often are described as going in the wrong direction. For example, if I understand the RFC correctly, OSPF type 4 LSAs are generated by ABRs, sent into non-backbone areas, and describe the ASBRS that are available in the AS. In the Cert Guide, type 4 LSAs are sent from the ABRs to ASBRs. That is done, according to the Cert Guide, so that the ASBR can send info on summary networks into other routing domains. So on and so on. Worst part of all is that the book is in its fourth printing and nothing has been done to fix it and there is no errata sheet on the Cisco Press web site. Having said all of that, the book is still borderline useful, but only if you already really know your stuff so you can see the many errors. I also read the Exam Cram book. It is a nice review but is very top-level, as you might expect. By the way, it is a myth that COLT exams are gone. I just tried one the other day.
