This chapter focuses on why we use specific design patterns to implement modularity, discussing specifically why we should use hierarchical design to create a modular network design, why we should use overlay networks to create virtualization, and the results of virtualization as a mechanism to provide modularity.
This chapter introduces strategies that can be used to systematically design a highly functional network, such as the hierarchical network design model, the Cisco Enterprise Architecture, and appropriate device selections.
With the exhaustion of the IPv4 addressing space quickly approaching, it has become a high priority for organizations to begin their own deployments of IPv6. This can be accomplished in a number of different ways. This article examines specific methods and how they can be used to support an IPv6 deployment.
This article focuses on the basic configuration of available IPv6 tunneling technologies for Cisco networks.
