| Understanding and troubleshooting CEF in Cisco routers and switches |
|
| How does a router switch a packet? What is the difference between |
| routing a packet, switching a frame, and packet switching? What is the |
| Cisco® Express Forwarding (CEF) feature referred to in Cisco |
| documentation and commonly found in Cisco IOS® commands? CEF is a |
| general term that describes the mechanism by which Cisco routers and |
| Catalyst® switches packet-switch (route) frames. CEF is found in |
| almost all Cisco routers and Catalyst switches, and understanding how |
| CEF operates can improve the performance, scalability, and efficiency |
| of your network. |
| Cisco Express Forwarding demystifies the internal workings of Cisco |
| routers and switches, making it easier for you to optimize performance |
| and troubleshoot issues that arise in Cisco network environments. This |
| book addresses common misconceptions about CEF and packet switching |
| across various platforms, helping you to improve your troubleshooting |
| skills for CEF- and non-CEF-related problems. |
| The first part of the book provides an overview of packet-switching |
| architectures and CEF operation and advanced features. It also covers |
| the enhanced CEF structure and general troubleshooting. The second |
| part of the book provides case studies that focus on the common topics |
| that have been problematic for customers and those supporting Cisco |
| networks. |
| Full of practical examples and configurations, this book draws on |
| years of experience to help you keep your Cisco networks running |
| efficiently. |
| Nakia Stringfield, CCIE® No. 13451, is a network consulting engineer |
| for Advanced Services at Cisco, supporting top financial customers |
| with network design and applying best practices. She was formerly a |
| senior customer support engineer for the Routing Protocols Technical |
| Assistance Center (TAC) team troubleshooting issues related to CEF and |
| routing protocols. Nakia has been with Cisco for more than six years, |
| previously serving as a technical leader for the Architecture TAC |
| team. |
| Russ White, CCIE No. 2635, is a Principle Engineer in the Routing |
| Protocol Design and Architecture team at Cisco. He is a member of the |
| IETF Routing Area Directorate, co-chair of the Routing Protocols |
| Security Working Group in the IETF, a regular speaker at Cisco |

| coauthor of six other books about routing and routing protocols, |
| including Optimal Routing Design from Cisco Press. Russ primarily |
| works in the development of new features and design architectures for |
| routing protocols. |
| Stacia McKee is a customer support engineer and technical leader of |
| the Routing Protocols Technical Assistance Center (TAC) team. This |
| team focuses on providing post-sales support of IP routing protocols, |
| MPLS, QoS, IP multicast, and many other Layer 3 technologies. Stacia |
| has been with Cisco for more than six years, previously serving as a |
| technical leader of the Architecture TAC team and a member of the WAN/ |
| Access TAC team. |
