This Cisco authorized textbook is a portable desk reference designed to complement the CCNP 1: Advanced Routing course in the Cisco Networking Academy Program.

CCNP 1: Advanced Routing is one of four courses leading to the CCNP certification. CCNP 1 teaches you how to design, configure, maintain, and scale routed networks.

Cisco Networking Academy Program CCNP 1: Advanced Routing Companion Guide, Second Edition, contains all the information from the online curriculum, with additional in-depth content to enhance your understanding of some topics, plus pedagogical aids to help you study.

You will learn to use VLSMs, private addressing, and NAT to enable more efficient use of IP addresses. This book also teaches you how to implement routing protocols such as RIPv2, EIGRP, OSPF, IS-IS, and BGP. In addition, this book details the important techniques used for route filtering and route redistribution. Use this Companion Guide to help prepare for the Building Scalable Cisco Internetworks exam (642-801 BSCI), which is one of the four required exams to obtain the CCNP certification.
