Hierarchical Network Design Overview (1.1) - Cisco Press
The Cisco hierarchical (three-layer) internetworking model is an industry wide adopted model for designing a reliable, scalable, and cost-efficient internetwork. In this section, you will learn about the access, distribution, and core layers and their role in the hierarchical network model.
Cisco Network Topologies and LAN Design
This chapter from CCDA Exam Certification Guide reviews the topologies used in network design and covers the technologies and design approaches used when designing a local-area network (LAN). The hierarchical, redundant, and secure topology models are covered.
Hierarchy Issues > Cisco Network Topology and Design | Cisco Press
Explore design issues related to overall network topology with this sample chapter from CCIE Professional Development: Large-Scale IP Network Solutions by Cisco Press.
Designing Scalable EIGRP Designs > Designing Cisco ... - Cisco Press
To scale EIGRP, it is a good idea to use a structured hierarchical topology with route summarization. One of the biggest stability and convergence issues with EIGRP is the propagation of EIGRP queries. When EIGRP does not have a feasible successor, it sends queries to its neighbors.
IS-IS Areas and Routing Hierarchies > Integrated IS-IS Routing …
IS-IS Areas and Routing Hierarchies. As specified in ISO 10589 and RFC 1195, the IS-IS protocol supports a two-level hierarchy for managing and scaling routing in large networks. A network domain can be carved out in a planned way or arbitrarily by the network designer or architect into small segments known as areas.
The Art of Network Architecture: Applying Modularity
2014年5月12日 · Hierarchical network design reaches beyond hub-and-spoke topologies at the module level and provides rules, or general methods of design, that provide for the best overall network design. This section discusses each of these methods or rules—but remember these are generally accepted rules, not hard and fast laws.
Typical Hierarchical Design Patterns - Cisco Press
There are two traditional hierarchical design patterns: two layer networks and three layer networks. These have been well covered in network design literature (for instance, see Optimal Routing Design), so we will provide only a high level overview of these two design patterns here.
Data Center Topologies > Data Center Design Overview - Cisco Press
This section discusses Data Center topologies and, in particular, the server farm topology. Initially, the discussion focuses on the traffic flow through the network infrastructure (on a generic topology) from a logical viewpoint and then from a physical viewpoint.
Implementing a Network Design (1.1) - Cisco Press
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.
