| Overview

Because many organizations are now seeking the economic benefits of campus networks for mission-critical communications, high reliability is becoming increasingly crucial. Within the campus network, much attention has been focused on providing a network infrastructure that is available 100 percent of the time. One of the greatest challenges does not come from the network infrastructure, but from the workstations and network equipment at the user level.

The objective of this module is to provide an overview of hardware and software redundancy operation and implementation on the Cisco Catalyst series of switches. The Cisco proprietary HSRP feature will be the main focus of this module with an overview of other software redundant technologies.
