This path instructs network administrators of medium-to-large network sites on the use of advanced IP addressing and routing in implementing scalability for Cisco routers connected to LANs and WANs. 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. It is an online, self-guided series designed to correlate to Cisco's own instructor led course BSCI 2.0. BSCI is part of the recommended training path for those students seeking the Cisco CCNP, CCDP, CCIP, and CCIE certifications.
