ahhh yes. That book is certainly one of those must-have from Cisco Press
in my opinion (may be not so related to CCIE studies, but more so in real life).
:) Barry and Phil in that book mostly speak straight out of experience, rather
than theoratical content which is what I enjoyed the most. Then they have the
whole sample topology and configuration set at the end.
I should look into the two other books you listed later on, thanks for the info!
