Lab : Syslog Server for Cisco Router in GNS3, Ch 15 : Virtual Router Redundancy Protocol. Chapter 2. A hierarchical network design involves dividing the network into discrete layers. If operators do not act now and prepare accordingly, they risk missing out. The design of the DC is very simplified as the network tiers are squeezed to a single switch layer 3 switch. JWD Campus Infrastructure Module The Campus Infrastructure module connects devices within a campus to the Data Center and Enterprise Edge modules. Core switches should have the following attributes: No costly or unnecessary packet manipulations (access lists, packet filtering), Redundancy and resilience for high availability. Core switches should have the following Designing a new network that has a hierarchy with three layers is fairly straightforward. —one connecting to each distribution switch. 2 See Figure 2-15 for a new network design drawing. These areas enable network designers and engineers to associate specific network functionality on equipment based upon its placement and function in the model. distribution block , named for the two switch layers that it contains. ■ Advanced QoS functions This chapter covers the following topics that you need to master for the CCNP SWITCH exam: Hierarchical Network Design—This section details a three-layer, hierarchical structure of campus network designs.. Modular Network Design—This section covers the process of designing a campus network, based on breaking it into functional modules. To reduce the size of a broadcast domain, you can segment a network or break it up into smaller Layer 2 VLANs. A company typically owns the entire campus network and the physical wiring. Suppose the segment contains hundreds of hosts . However, the emphasis should be on providing an overall design that is into a hierarchical design. Enterprise Campus The hierarchical network model supports designing a highly available modular topology using scalable building blocks that allow the network to meet evolving business needs. End users connect at this layer. Layer 2. Enterprise Network Campus Design (1.1.1) An understanding of network scale and knowledge of good structured engineering principles is recommended when discussing network campus design. Chapter 12. Due the criticality of the core layer, the design principles of the core should provide an appropriate level of resilience that offers the ability to recover quickly and smoothly after any network failure event with the … The resulting network is, does not address other best practices like. The networking equipments (switches, routers) and transmission media (optical fiber, copper plant, Cat5 cabling etc.) In Figure 4-1 , the topology is stable and easy to expand and maintain.

Network design is an expanding area and requires a great deal of knowledge and experience. The campus network’s backbone, which connects all switch blocks. To limit the size of a collision domain, you can connect smaller numbers of hosts to individual switch interfaces. To mitigate the effects of a core switch failure, you can add a second, redundant core switch. Enterprise Campus The hierarchical network model supports designing a highly available modular topology using scalable building blocks that allow the network to meet evolving business needs. ■ Security features and quality of service, The distribution layer provides interconnection between the campus network’s access and core layers. If that core switch fails, users in the access layer will still be able The sample high-level topology diagram is for a large enterprise network that consists of a main campus site connecting small, medium, and large sites. 1. Traffic flows in a enterprise networks can be classified as three types: core, The dashed rectangle in Above Figures represent The resulting network is organized, efficient, and predictable. - A company typically owns the entire campus network and the physical wiring. Designing an Enterprise Campus The Enterprise Campus network is the foundation for enabling business applications, enhancing A typical hierarchical enterprise campus network design includes the following three layers: Core layer: Provides optimal transport between sites and high-performance routing. These units, The core sometimes referred to as the backbone. First, you'll discover how to layer two campus design concepts, such as VLANs, spanning-tree protocol, and topologies. 4.2.1. Across all switch ports c. On a single VLAN d. Across all VLANs Answer: A 2. You can divide enterprise campus networks into the following basic elements or building blocks: A group of access layer switches, together with their distribution switches. Switch interfaces do not propagate collisions, so each interface becomes its own collision domain—even if several interfaces belong to a common VLAN. In fact, broadcast frames will reach every switch interface in a VLAN. A switch block consists of two distribution switches that aggregate one or more access layer switches. ■ Redundancy and resilience for high availability Redundant links A collection of PCs, printers, and servers are all connected to the same network segment and use the 192.168.1.0 subnet. At enterprise campus network we have access network contain the end devices like PCs and laptop. Layer 2 access layer. Access switches usually provide Layer 2 (VLAN) connectivity between users. In this course, Enterprise Campus Network Design for Cisco CCDP ARCH (300-320), you'll learn the foundations of designing enterprise campus networks. . Users might have connectivity additions to the network need to be added. There are two ways to design Enterprise Network i.e To contain broadcast traffic, the idea is to provide a barrier at the edge of a LAN segment so that broadcasts cannot pass or be forwarded outward. Access Layer In-Depth switches are aggregated into a single distribution layer switch. A campus network’s core layer provides connectivity between all distribution layer devices.

A switch block is too large if the following conditions are observed: The routers (multilayer switches) at the distribution layer become traffic bottlenecks, because : switching times required by policy or security functions (access lists, queuing, and so on). The access layer exists where the end users are connected to the network. Each layer of the network is connected to the adjacent connectivity between users. The modular design makes the network easy to scale, understand, and troubleshoot by promoting deterministic traffic patterns . Enterprise Campus The hierarchical network model supports designing a highly available modular topology using scalable building blocks that allow the network to meet evolving business needs. Designing Campus Networks A campus network is a building or group of buildings all connected into one enterprise network that consists of many local-area networks (LANs). Devices in this layer should have the following capabilities: Ability to converge network services (that is, data, voice, video), Security features and quality of service (QoS). The resulting network is organized, efficient, and predictable. the redundant design i.e the core layer has only one switch. One weakness is still present in MLS-sw1 has a limited number of ports, so it cannot directly connect to every device. approach. A campus network’s core layer provides connectivity between all distribution layer devices. Where does a collision domain exist in a switched network? A campus network is an enterprise network consisting of many LANs in one or more buildings, all connected and all usually in the same geographic area. ■ Scalable uplinks to higher layers a. CCNP Switch FAQ : Enterprise Campus Network Design 1. Broadcast or multicast traffic slows the switches in the switch block. Access Layer. Hierarchical model of campus network design The so-called 'hierarchical' model is to divide the complex network design into several levels, each of which focuses on certain specific functions, which can make a complex big problem into many simple small problems. With so many interconnecting links between switches, it becomes a “brain-buster” exercise to figure out where VLANs are trunked, what Both the server farm and the mainframe are considered enterprise resources. The enterprise network comprises two functional areas, which are the enterprise campus and the enterprise edge. 1. functions that define its role within the overall network. Simple Shared Ethernet Network. On a single switch port b. All devices on this network segment must share the available bandwidth. If a link fails, a significant portion of the network will become isolated. Simple Shared Ethernet Network Cisco Hierarchical Network Design Principles. 1. High Availability Design The midsize enterprise campus solution is designed to provide users with uninterrupted network access during hardware or software failures. The sample high-level topology diagram is for a large enterprise network that consists of a main campus site connecting small, medium, and large sites. should also be added between each distribution layer switch and each core layer switch.
