4 Target Audience Those desiring to continue their post-ccna preparation for a career as a network administrator, Level 2 support engineer, Level 2 systems engineer, network technician, or deployment engineer. CCNA certified individuals pursuing CCNP, CCIP, CCSP, CCDP, or CCIE certifications. Prerequisites Students should have completed CCNA 1 4 or equivalent. CCNA Certification desired but not required. Work experience beneficial. Course Description CCNP: Building Scalable Internetworks is the first of four courses leading to the Cisco Certified Network Professional (CCNP) designation. CCNP: Building Scalable Internetworks introduces Cisco Networking Academy Program students to scalable IP networks. Students will learn how to create an efficient and expandable enterprise network by installing, configuring, monitoring, and troubleshooting network infrastructure equipment (especially routers such as Cisco ISRs) according to the Campus Infrastructure module in the Enterprise Composite Network model. Topics include how to configure EIGRP, OSPF, IS-IS, and BGP routing protocols and how to manipulate and optimize routing updates between these routing protocols. Other topics include multicast routing, IPv6, and DHCP configuration. Course Objectives The CCNP certification indicates knowledge of networking for the small-office, home-office (SOHO) market and enterprise markets and the ability to work in businesses or organizations whose networks have between 100 and 500 nodes. A CCNP certified individual should be able to: Implement appropriate technologies to build a scalable routed network Build campus networks using multilayer switching technologies Improve traffic flow, reliability, redundancy, and performance for campus LANs, routed and switched WANs, and remote access networks Create and deploy a global intranet Troubleshoot an environment that uses Cisco routers and switches for multiprotocol client hosts and services 3 CCNP: Building Scalable Internetworks v5.0 Copyright 2006, Cisco Systems, Inc.

5 Perform entry-level tasks in the planning, design, installation, operation and troubleshooting of Ethernet, TCP/IP networks. CCNP: Building Scalable Internetworks is an integral step towards achieving CCNP Certification. Upon completion of this course, students will have performed tasks related to: Internetwork scalability Routing protocol operation, configuration, and troubleshooting EIGRP, OSPF, IS-IS, BGP Route optimization IP Multicast IPv6 Lab Requirements Please refer to the CCNP Equipment Bundle Spreadsheets on Cisco Academy Connection (CAC) Certification Alignment The curriculum is aligned with ILSGs BSCI course and the exam. Course Overview The course is designed to be delivered in a 70 contact hour time frame. Approximately 45 hours will be designated to lab activities and 25 hours on curriculum content. A case study on advanced routing is required, but format and timing are determined by the Local Academy. 4 CCNP: Building Scalable Internetworks v5.0 Copyright 2006, Cisco Systems, Inc.
