Description:

Quote:

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梖rom 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
