(Enterprise campuses of any size need a highly available and secure, intelligent network infrastructure to support business solutions such as voice, video, wireless and mission-critical data usage. Providing this reliable network infrastructure requires minimal disruption to operations caused by the failure of the components that make up the entire system of the campus. Understanding how a system recovers from component outages (including intra-scheme outages and failures), and the behavior that may result during an outage, is undoubtedly a critical step in the design, upgrade, and operation of a highly available and secure campus network. This article provides an analysis of the failure recovery of the campus network designs described in these articles and includes the following chapters: Overview, Page 2 Convergence of the Layer 3 Core - Results and Analysis, Page 7 Layer 3 Distribution and Layer 2 Convergence of Access - Results and Analysis, p. 12 Convergence of Layer 3 Distribution and Layer 3 Routable Access - Results and Analysis, p. 33 Configurations Tested, p. 41 Intended Audience Who Should Read This Article As a Cisco systems engineer and customer engineer responsible for campus network design, this article also helps operations and other staff understand the possible convergence behavior of existing production campus networks.
