Cisco CCIE fundamentals: network design and case studies

This two-part reference is a compilation of design tips and configuration examples assembled by Cisco over the course of several years of networking experience. It was most recently updated for this release as a Cisco Press book by four highly experienced CCIEs with extensive expertise in the technologies addressed in this collection. The design guide protion of this book is intended to support the network administrator who designs and implements routers and switched-based networks. The case study portion of this book supplements the design guide material with real-world configurations.
