Official Cisco Training - Building Scalable Cisco Internetworks 3.0 (BSCI)

Course Overview

Building Scalable Cisco Internetworks (BSCI) v3.0 is recommended advanced routing training for individuals seeking certification as a Cisco CCNP®. BSCI instructs network administrators of medium-to-large network sites on the use of advanced IP addressing and routing in implementing scalability for Cisco routers that are connected to LANs and WANs. The BSCI v3.0 course has eight modules, with several lessons per module and numerous hands-on labs. The goal is to train network administrators to dramatically increase the number of routers and sites
using these techniques instead of redesigning the network when additional sites or wiring configurations are added.
