OSPF and IS-IS: Choosing an IGP for Large-Scale Networks: Choosing an IGP for Large-Scale Networks: Choosing an IGP for Large-Scale Networks: Choosing an IGP for Large-Scale Networks

Product Description

This is the definitive guide to using OSPF and IS-IS protocols in large-scale IP enterprise, carrier, and service provider networks. Well-known network designer Jeff Doyle draws on his consulting experience, offering realistic advice and straight answers on every aspect of working with link-state protocols – from scalability, reliability, and security to area design and database synchronization. This book is organized to help network engineers and architects compare OSPF and IS-IS. One feature at a time, Doyle first demonstrates how a topic or feature is implemented in OSPF, and then walks through a similar implementation using IS-IS. Professionals who are relatively new to large-scale networking will welcome his practical introduction to the concepts, goals, and history of link state protocols.

The practical guide to large-scale networking with OSPF and IS-IS
This is the definitive guide to using OSPF and IS-IS protocols in large-scale IP enterprise, carrier, and service provider networks. Well-known network designer Jeff Doyle draws on his consulting experience, offering realistic advice and straight answers on every aspect of working with link-state protocols―from scalability, reliability, and security to area design and database synchronization.
This book is organized to help network engineers and architects compare OSPF and IS-IS. One feature at a time, Doyle first demonstrates how a topic or feature is implemented in OSPF, and then walks through a similar implementation using IS-IS. Professionals who are relatively new to large-scale networking will welcome his practical introduction to the concepts, goals, and history of link state protocols. Coverage includes

Understanding message types, encapsulation, architecture, LSAs, and LSPs
Optimizing addressing, neighbor discovery, adjacencies, and router designation
Improving scalability: controlling the scope of flooding, link state database size, SPF calculation efficiency, and much more
Designing and operating large-scale networks for maximum security and reliability
Hardening networks to thwart attacks against routing protocols
Comparing OSPF and IS-IS extensibility
Utilizing extensions for MPLS-based traffic engineering, IPv6, and multi-topology routing
Troubleshooting OSPF and IS-IS log entries, debug output, and LS databases

Doyle’s thorough explanations, end-of-chapter review questions, and many wide-ranging examples for both Cisco’s IOS and Juniper’s JUNOS also make this book an exceptional resource for anyone pursuing a CCIE or JNCIE certification.

Preface
This book is an expansion of a PowerPoint presentation I have used for years in design meetings for IP carrier and service provider networks, comparing and contrasting OSPF and IS-IS. The PowerPoint presentation in turn grew from numerous informal chalk talks I had done fo
