IP Routing Protocols All-in-one: OSPF EIGRP IS-IS BGP Hands-on Labs

OSPF, IS-IS, EIGRP and BGP routing protocols are the heart of IP routing and the internet itself.
This practical guide offers a series of labs to cover the features of each routing protocol and how to optimize it for scalability and performance improvement in term of processing. By going step by step, the scenarios are enriched with concise explanations for each step.

Goals and Methods:

Focusing on Cisco Routers, the book shows how to implement and optimize OSPF, IS-IS, EIGRP and BGP by exploring:

• OSPF: Area Types with optimization, LSA Types, the logic of Intra-area, inter-area and external routes, Virtual-link and route filtering, Loop Prevention mechanisms and MPLS with the concepts of sham link and Down bit.

• EIGRP: concept of stub and maximum prefix limit for optimization, route filtering using different methods, route leaking, in-depth exploration of successor and feasible successor, EIGRP Named Mode and redistribution between two autonomous systems.

• IS-IS: concept of Level 1 and Level 2 routes, IS-IS adjacencies and DIS in broadcast network, the logic of intra-area and inter-area routes, route leaking and ATT bit.

• BGP: attributes and path selection, exploration of MED, Local Preference, weight, AS-path and community attributes, route filtering and ORF (Outbound Route Filtering), Attribute-map and Unsuppress-map, confederation, peer group and route reflector features.

Through all these scenarios covering all the stuff covered above, the book is good resource to cement the theory you learned. It transforms what you have learned in your study guides into valuable skills you will be using from day one on your job as a network engineer.

Knowing the theory alone is no longer enough to master routing protocols. Mastering the practice part is very important to be able to configure, troubleshoot routing protocols where you must quickly and accurately diagnose and repair network faults on routers.

How to read this book?

This book is a series of hands of labs, and there is no relationship between them, you can start at any lab, from the last, the first or the middle, the purpose is to provide you a granularity to freely switch between topics and go to the one you need in depth lecture and understanding.

It is very important that you should have a strong skills theory for each routing protocol because the book goes straight forward to lab.
