Routing Tcp Ip- Volume Ii -ccie Professional Development 〈PREMIUM · How-To〉

(Chapter titles paraphrased—book contains deep, protocol-level treatment and configuration examples.)

Doyle masterfully explains the paradigm shift. In Volume I (OSPF/EIGRP), you trust everyone. In Volume II (BGP), you trust no one. The book breaks down Autonomous Systems (ASs) and why the internet is a federation of warring tribes rather than a single country.

Aimed at experienced network engineers preparing for advanced routing/CCIE-level topics, this book focuses on interior and exterior routing protocols, design principles, configuration considerations, and scalable implementation details beyond protocol basics.

Chapter 6: BGP and Multiprotocol BGP (MP-BGP)

A critical component of Volume II, which became increasingly relevant as the industry evolved, is its treatment of Multiprotocol BGP (MP-BGP).

Historically, BGP was strictly an IPv4 unicast protocol. However, the authors anticipated the direction of the industry. MP-BGP extends BGP’s capabilities to carry reachability information for other protocols, most notably IPv6 and MPLS VPNs. Chapter 2: BGP Operation

For the modern CCIE, this section is vital. It connects the "old world" of pure Internet routing to the "new world" of Service Provider backbones and L3VPN architectures. It explains how BGP becomes the control plane for label switching, a concept that underpins modern data center fabrics and provider core networks.

While Volume I focused on IGPs (RIP, EIGRP, OSPF, IS-IS), Volume II is dominated by the heavyweights of Exterior Gateway Protocols (EGPs) and the nuanced mechanics of large-scale route manipulation.

1. Domain Name System (DNS) Uniquely, Doyle dedicates significant space to DNS. He treats it not as a separate service but as an integral part of the routing infrastructure—understanding how names map to routes is critical for advanced network debugging.

2. Border Gateway Protocol (BGP) - The Core Focus Over half of this volume is a masterclass in BGP-4, the protocol that runs the internet. Doyle dissects every facet:

3. Advanced Route Manipulation

4. IP Multicast (IGMP & PIM) The book provides a robust introduction to multicast routing, covering Internet Group Management Protocol (IGMP) and Protocol Independent Multicast (PIM) in Sparse and Dense modes—critical for modern video and data distribution networks.

5. IPv6 Routing Addressing the transition from IPv4, Doyle covers the routing aspects of IPv6, including OSPFv3, EIGRP for IPv6, and the intricacies of integrating BGP in a dual-stack world. While not as exhaustive as Volume I’s IPv4 treatment, it provides the foundational knowledge needed for the CCIE lab.

Before we dissect the chapters, we must address a common question: Is a book from 2004 (Updated in 2016) still relevant?

The answer is an emphatic yes. Unlike application-layer frameworks that change every six months, routing protocols are the grammar of networking. BGP-4, the core of Volume II, hasn't changed significantly because it cannot change without breaking the internet.

The CCIE Professional Development series does not teach you to pass a multiple-choice test. It teaches you to troubleshoot a broken BGP route reflector cluster at 2:00 AM using a packet capture. This book focuses on the why behind the configuration. Chapter 3: BGP Configuration and Troubleshooting
