Information In this tech paper, you will learn about the key protocols for building a redundant network and discover—based on five examples—how to design highly available three-tier or two-tier networks
Information By using extra hardware, businesses maintain high availability and customer trust. This diagram shows how to build a reliable network using redundant routers and switches. This template showcases a
Information Installing two new firewalls that work together in a master/slave configuration, so we have redundancy at our firewall level. Our service provider has already provided us with two different links
Information The main goal of STP is to disable as many redundant links as necessary in the topology but still provide active links to each part of the network (see the example topology above).
Information Figure 1. An Ethernet switch flooding unknown unicast frames. The main idea here is simple - if you don''t know where exactly to deliver a frame, send it out everywhere, and the intended recipient will
Information In the core layer, I want to have redundancy, which means that if the main core switch of my network has a problem, the backup switch will automatically enter the circuit.
Information Redundant paths between the ISP, routers, and switches provide fault tolerance. The layout ensures high availability. It does this by removing single points of failure with duplicated
Information In this section, you will learn how to build a simple switched network with redundant links. The focus of this topic is to describe how Spanning Tree Protocol can solve common looping
Information Core Layer: Two Cisco 3560 Multilayer Switches (Switch0 and Switch1) act as the core/distribution layer with inter-switch links for redundancy. Access Layer: Two Cisco 2960 switches
Information The three-tier hierarchical network design that uses core, distribution, and access layers with redundancy attempts to eliminate a single point of failure on the net-work.
