This course is the second in the Cisco Academy CCNA Routing and Switching curriculum. CSO-155 describes the architecture, components, and operations of routers and switches in a small network. Students learn how to configure a router and a switch for basic functionality. By the end of this course, students will be able to configure and troubleshoot routers and switches and resolve common issues with RIPv1, RIPv2, single-area OSPF, VLANs, and interVLAN routing in both IPv4 and IPv6 networks.
