This course describes the architecture, components, and operations of routers and switches in a large and complex network. You will learn how to configure routers and switches for advanced functionality. By the end of this course, you will be able to configure and troubleshoot routers and switches and resolve common issues with OSPF, EIGRP, STP, and VTP in both IPv4 and IPv6 networks. You will also develop the knowledge and skills needed to implement DHCP and DNS operations in a network.
The Companion Guide is designed as a portable desk reference to use anytime, anywhere to reinforce the material from the course and organize your time.
The book's features help you focus on important concepts to succeed in this course:
Chapter objectives-Review core concepts by answering the focus questions listed at the beginning of each chapter.
