After my first publication of the book OSPF Demystified With RFC in 2014 which goes beyond the CCIE level which explores OSPF from the RFC’s perspective. Since one year I had the idea to write a book for CCIE Enterprise and Infrastructure to be an ultimate preparation to enforce candidates’s skills and to acquire solid knownledges after attending a global preparation or in depth bootcamp, this why I call it OSPF The Ultimate.
The idea is to offer a series of 30 practice labs that covers all the blueprint of the lab exam with high level scenarios, and to acquire additional scenarios and an indepth exploration of the most important OSPF’s concept related to the exam such as LSA Types in details by analysing the most important fields, Area Types, Network Types OSPF Path Selection (with many tricky scenarios), Route Filtering (with many tricky scenarios), Forwarding Address, Prefix Suppression, Loop-Free Alternate, Summary Routes and so on . Also I given a way to be able to reproduce them using the basic configuration present at the top of each lab.
The ultimate goals is:
To be able to troubleshoot any problem by reasoning.
To be able to answer challenges that requires only one command.
How to follow some logic to detect any problem or to explain an unexpected behavior.
How to fix it with some restrictions such as: you are not allowed to use cost and so on.
