These books are well written and contain all the information you will need to pass the CCNP V2 exams. One major caveat though: they are full of errors and often in very unfortunate places. Errors that serve to confuse the text to the point of serious detriment to readers who are not active in the maintaining of the most recent errata. Be aware, there are points in the books where important topics are being explained and right at the punch line, a serious and sometimes blatant error appears. There are even whole sections in the ROUTE book that are incorrect, such as the explanation of the 'area <area-num> range' and 'summary-address' OSPF commands in relation to default route propagation. If at any point reading the books you are mystified, check the errata.
Note: More recent printings may have cleared many of the errors?
