    Implementing Cisco IP Switched Networks (SWITCH) Foundation Learning Guide: Network Design Fundamentals | existent questions and Pass4sure dumps

    This chapter from Implementing Cisco IP Switched Networks (SWITCH) Foundation Learning Guide: (CCNP SWITCH 300-115) begins the journey of exploring campus network design fundamentals by focusing on a few core concepts around network design and structure and a few details about the architecture of Cisco switches. This chapter is from the reserve 

    Every time you trail to an office to travail or trail to class at school, college, or university, you will utilize a campus network to access captious applications, tools, the Internet, and so on over wired or wireless connections. Often, you may even gain access by using a portable device such as an Apple iPhone connected on a corporate Wi-Fi to gain applications such as e-mail, calendaring, or instant messaging over a campus network. Therefore, the persons amenable for edifice this network requisite to deploy sound fundamentals and design principles for the campus networks to role adequately and provide the necessary stability, scalability, and resiliency necessary to sustain interconnectivity with a 100 percent uptime.

    This chapter begins the journey of exploring campus network design fundamentals by focusing on a few core concepts around network design and structure and a few details about the architecture of Cisco switches. This is useful scholarship when designing and edifice campus networks. Specifically, this chapter focuses on the following two high-level topics:

  • Campus network structure
  • Introduction to Cisco switches and their associated architecture
  • A campus network describes the portion of an enterprise infrastructure that interconnects cease devices such as computers, laptops, and wireless access points to services such as intranet resources or the Internet. Intranet resources may breathe company web pages, call heart applications, file and print services, and almost anything cease users connect to from their computer.

    In different terms, the campus network provides for connectivity to company applications and tools that reside in a data heart for cease users. Originally, prior to around 2005, the term campus network and its architectures were apposite for application server farms and computing infrastructure as well. Today, the infrastructure that interconnects server farms, application servers, and computing nodes are clearly distinguished from campus networks and referred to as data centers.

    Over the past few years, data heart architectures believe become more complex and require sophistication not required in the campus network due to high-availability, low-latency, and high-performance requirements. Therefore, data centers may utilize bleeding-edge technologies that are not institute in the campus network, such as FabricPath, VXLAN, and Application Centric Infrastructure (ACI). For the purpose of CCNP Switch at the time of this writing, these technologies, as well as data heart architectures, are out of scope. Nevertheless, they will point out some of the differences as to avoid any confusion with campus network fundamentals.

    The next subsection describes the hierarchical network design with the following subsections breaking down the components of the hierarchical design in detail.

    Hierarchical Network Design

    A flat enterprise campus network is where everything PCs, servers, and printers are connected to each other using Layer 2 switches. A flat network does not utilize subnets for any design purposes. In addition, everything devices on this subnet are in the very broadcast domain, and broadcasts will breathe flooded to everything attached network devices. Because a broadcast packet received by an cease device, such as tablet or PC, uses compute and I/O resources, broadcasts will dissipate available bandwidth and resources. In a network size of ten devices on the very flat network, this is not a significant issue; however, in a network of thousands of devices, this is a significant dissipate of resources and bandwidth (see pattern 2-1).

    Figure 2-1

    Figure 2-1 Flat Versus Hierarchical Network Design

    As a result of these broadcast issues and many other limitations, flat networks finish not scale to meet the needs of most enterprise networks or of many diminutive and medium-size businesses. To address the sizing needs of most campus networks, a hierarchical model is used. pattern 2-2 illustrates, at a high level, a hierarchical view of campus network design versus a flat network.

    Hierarchical models for network design allow you to design any networks in layers. To understand the second of layering, reckon the OSI reference model, which is a layered model for understanding and implementing computer communications. By using layers, the OSI model simplifies the stint that is required for two computers to communicate. Leveraging the hierarchical model also simplifies campus network design by allowing focus at different layers that build on each other.

    Referring to pattern 2-2, the layers of the hierarchical model are divided into specific functions categorized as core, distribution, and access layers. This categorization provides for modular and springy design, with the capacity to grow and scale the design without major modifications or reworks.

    For example, adding a unusual wing to your office edifice may breathe as simple as adding a unusual distribution layer with an access layer while adding capacity to the core layer. The existing design will stay intact, and only the additions are needed. Aside from the simple physical additions, configuration of the switches and routes is relatively simple because most of the configuration principles around hierarchy were in space during the original design.

    By definition, the access, distribution, and core layer adhere to the following characteristics:

  • Access layer: The access layer is used to grant the user access to network applications and functions. In a campus network, the access layer generally incorporates switched LAN devices with ports that provide connectivity to workstations, IP phones, access points, and printers. In a WAN environment, the access layer for teleworkers or remote sites may provide access to the corporate network across WAN technologies.
  • Distribution layer: The distribution layer aggregates the access layer switches wiring closets, floors, or other physical domain by leveraging module or Layer 3 switches. Similarly, a distribution layer may aggregate the WAN connections at the edge of the campus and provides policy-based connectivity.
  • Core layer (also referred to as the backbone): The core layer is a high-speed backbone, which is designed to switch packets as hasty as possible. In most campus networks, the core layer has routing capabilities, which are discussed in later chapters of this book. Because the core is captious for connectivity, it must provide a high level of availability and meet to changes quickly. It also provides for dynamic scalability to accommodate growth and hasty convergence in the event of a failure.
  • The next subsections of this chapter recount the access layer, distribution layer, and core layer in more detail.

    Access Layer

    The access layer, as illustrated in pattern 2-3, describes the logical grouping of the switches that interconnect cease devices such as PCs, printers, cameras, and so on. It is also the space where devices that extend the network out one more level are attached. Two such prime examples are IP phones and wireless APs, both of which extend the connectivity out one more layer from the actual campus access switch.

    The wide variety of workable types of devices that can connect and the various services and dynamic configuration mechanisms that are necessary upshot the access layer one of the most capable parts of the campus network. These capabilities are as follows:

  • High availability: The access layer supports high availability via default gateway redundancy using dual connections from access switches to redundant distribution layer switches when there is no routing in the access layer. This mechanism behind default gateway redundancy is referred to as first-hop redundancy protocol (FHRP). FHRP is discussed in more detail in later chapters of this book.
  • Convergence: The access layer generally supports inline Power over Ethernet (PoE) for IP telephony, thin clients, and wireless access points (APs). PoE allows customers to easily space IP phones and wireless APs in strategic locations without the requisite to sprint power. In addition, the access layers allow advocate for converged features that enable optimal software configuration of IP phones and wireless APs, as well. These features are discussed in later chapters.
  • Security: The access layer also provides services for additional security against unauthorized access to the network by using tools such as port security, attribute of service (QoS), Dynamic Host Configuration Protocol (DHCP) snooping, dynamic ARP inspection (DAI), and IP Source Guard. These security features are discussed in more detail in later chapters of this book.
  • The next subsection discusses the upstream layer from the access layer, the distribution layer.

    Distribution Layer

    The distribution layer in the campus design has a unique role in which it acts as a services and control limit between the access layer and the core. Both the access layer and the core are essentially dedicated special-purpose layers. The access layer is dedicated to meeting the functions of end-device connectivity, and the core layer is dedicated to providing nonstop connectivity across the entire campus network. The distribution layer, in contrast, serves multiple purposes. pattern 2-4 references the distribution layer.

    Availability, hasty path recovery, load balancing, and QoS are everything primary considerations at the distribution layer. Generally, high availability is provided through Layer 3 redundant paths from the distribution layer to the core, and either Layer 2 or Layer 3 redundant paths from the access layer to the distribution layer. maintain in mind that Layer 3 equal-cost load sharing allows both uplinks from the distribution to the core layer to breathe used for traffic in a variety of load-balancing methods discussed later in this chapter.

    With a Layer 2 design in the access layer, the distribution layer generally serves as a routing limit between the access and core layer by terminating VLANs. The distribution layer often represents a redistribution point between routing domains or the demarcation between static and dynamic routing protocols. The distribution layer may achieve tasks such as controlled routing conclusion making and filtering to implement policy-based connectivity, security, and QoS. These features allow for tighter control of traffic through the campus network.

    To improve routing protocol performance further, the distribution layer is generally designed to summarize routes from the access layer. If Layer 3 routing is extended to the access layer, the distribution layer generally offers a default route to access layer switching while leveraging dynamic routing protocols when communicating with core routers.

    In addition, the distribution layer optionally provides default gateway redundancy by using a first-hop routing protocol (FHRP) such as Host Standby Routing Protocol (HSRP), Gateway Load Balancing Protocol (GLBP), or Virtual Router Redundancy Protocol (VRRP). FHRPs provide redundancy and high availability for the first-hop default gateway of devices connected downstream on the access layer. In designs that leverage Layer 3 routing in the access layer, FHRP might not breathe applicable or may require a different design.

    In summary, the distribution layer performs the following functions when Layer 3 routing is not configured in the access layer:

  • Provides high availability and equal-cost load sharing by interconnecting the core and access layer via at least dual paths
  • Generally terminates a Layer 2 domain of a VLAN
  • Routes traffic from terminated VLANs to other VLANs and to the core
  • Summarizes access layer routes
  • Implements policy-based connectivity such as traffic filtering, QoS, and security
  • Provides for an FHRP
  • Core Layer (Backbone)

    The core layer, as illustrated in pattern 2-5, is the backbone for campus connectivity, and is the aggregation point for the other layers and modules of an enterprise network. The core must provide a high level of redundancy and meet to changes quickly.

    From a design point-of-view, the campus core is in some ways the simplest yet most captious Part of the campus. It provides a limited set of services and is designed to breathe highly available and requires 100 percent uptime. In big enterprises, the core of the network must operate as a nonstop, always-available service. The key design objectives for the campus core are based on providing the arrogate level of redundancy to allow for near-immediate data-flow recovery in the event of the failure of any component (switch, supervisor, line card, or fiber interconnect, power, and so on). The network design must also permit the occasional, but necessary, hardware and software upgrade or change to breathe made without disrupting any network applications. The core of the network should not implement any complex policy services, nor should it believe any directly attached user or server connections. The core should also believe the minimal control plane configuration that is combined with highly available devices that are configured with the redress amount of physical redundancy to provide for this nonstop service capability. pattern 2-6 illustrates a big campus network interconnected by the core layer (campus backbone) to the data center.

    From an enterprise architecture point-of-view, the campus core is the backbone that binds together everything the elements of the campus architecture to include the WAN, the data center, and so on. In other words, the core layer is the Part of the network that provides for connectivity between cease devices, computing, and data storage services that are located within the data center, in addition to other areas and services within the network.

    Figure 2-7 illustrates an instance of the core layer interconnected with other parts of the enterprise network. In this example, the core layer interconnects with a data heart and edge distribution module to interconnect WAN, remote access, and the Internet. The network module operates out of company from the network but is noiseless a captious component.

    Figure 2-7

    Figure 2-7 Core Layer Interconnecting with the Enterprise Network

    In summary, the core layer is described as follows:

  • Aggregates the campus networks and provides interconnectivity to the data center, the WAN, and other remote networks
  • Requires high availability, resiliency, and the capacity to upshot software and hardware upgrades without interruption
  • Designed without direct connectivity to servers, PCs, access points, and so on

  • Layer 3 in the Access Layer

    As switch products become more commoditized, the cost of Layer 3 switches has diminished significantly. Because of the reduced cost and a few inherit benefits, Layer 3 switching in the access layer has become more common over typical Layer 2 switching in the access layer. Using Layer 3 switching or traditional Layer 2 switching in the access layer has benefits and drawbacks. pattern 2-8 illustrates the comparison of Layer 2 from the access layer to the distribution layer with Layer 3 from the access layer to the distribution layer.

    As discussed in later chapters, deploying a Layer 2 switching design in the access layer may result in suboptimal usage of links between the access and distribution layer. In addition, this fashion does not scale as well in very big numbers because of the size of the Layer 2 domain.

    Using a design that leverages Layer 3 switching to the access layer VLANs scales better than Layer 2 switching designs because VLANs acquire terminated on the access layer devices. Specifically, the links between the distribution and access layer switches are routed links; everything access and distribution devices would participate in the routing scheme.

    The Layer 2-only access design is a traditional, slightly cheaper solution, but it suffers from optimal utilize of links between access and distribution due to spanning tree. Layer 3 designs introduce the challenge of how to sunder traffic. (For example, guest traffic should stay separated from intranet traffic.) Layer 3 designs also require observant planning with respect to IP addressing. A VLAN on one Layer 3 access device cannot breathe on another access layer switch in a different Part of your network because each VLAN is globally significant. Traditionally, mobility of devices is limited in the campus network of the enterprise in Layer 3 access layer networks. without using an advanced mobility networking features.

    In summary, campus networks with Layer 3 in the access layer are becoming more popular. Moreover, next-generation architectures will alleviate the biggest problem with Layer 3 routing in the access layer: mobility.

    The next subsection of this chapter applies the hierarchical model to an enterprise architecture.

    The Cisco Enterprise Campus Architecture

    The Cisco enterprise campus architecture refers to the traditional hierarchical campus network applied to the network design, as illustrated in pattern 2-9.

    The Cisco enterprise campus architecture divides the enterprise network into physical, logical, and functional areas while leveraging the hierarchical design. These areas allow network designers and engineers to associate specific network functionality on paraphernalia that is based on its placement and role in the model.

    Note that although the tiers finish believe specific roles in the design, no absolute rules apply to how a campus network is physically built. Although it is trusty that many campus networks are constructed by three physical tiers of switches, this is not a strict requirement. In a smaller campus, the network might believe two tiers of switches in which the core and distribution elements are combined in one physical switch: a collapsed distribution and core. However, a network may believe four or more physical tiers of switches because the scale, wiring plant, or physical geography of the network might require that the core breathe extended.

    The hierarchy of the network often defines the physical topology of the switches, but they are not the very thing. The key principle of the hierarchical design is that each ingredient in the hierarchy has a specific set of functions and services that it offers and a specific role to play in the design.

    In reference to CCNP Switch, the access layer, the distribution layer, and core layer may breathe referred to as the edifice access layer, the edifice distribution layer, and the edifice core layer. The term edifice implies but does not limit the context of layers as physical buildings. As mentioned previously, the physical demarcation does not believe to breathe a building; it can breathe a floor, group of floors, wiring closets, and so on. This reserve will solely utilize the terms access layer, distribution layer, and core layer for simplicity.

    In summary, network architects build Cisco enterprise campus networks by leveraging the hierarchical model and dividing the layers by some physical or logical barrier. Although campus network designs trail much further beyond the basic structure, the key takeaway of this section is that the access, distribution, and core layers are applied to either physical or logical barriers.

    The requisite for a Core Layer

    When first studying campus network design, persons often question the requisite for a core layer. In a campus network contained with a few buildings or a similar physical infrastructure, collapsing the core into the distribution layer switches may rescue on initial cost because an entire layer of switches is not needed. pattern 2-10 shows a network design instance where the core layer has been collapsed into the distribution layer by fully meshing the four sunder physical buildings.

    Despite a workable lower cost to the initial build, this design is difficult to scale. In addition, cabling requirements enlarge dramatically with each unusual edifice because of the requisite for full-mesh connectivity to everything the distribution switches. The routing complexity also increases as unusual buildings are added because additional routing peers are needed.

    With admiration to pattern 2-10, the distribution module in the second edifice of two interconnected switches requires four additional links for full-mesh connectivity to the first module. A third distribution module to advocate the third edifice would require 8 additional links to advocate the connections to everything the distribution switches, or a total of 12 links. A fourth module supporting the fourth edifice would require 12 unusual links for a total of 24 links between the distribution switches.

    As illustrated in pattern 2-11, having a dedicated core layer allows the campus to accommodate growth without requiring full-mesh connectivity between the distribution layers. This is particularly primary as the size of the campus grows either in number of distribution blocks, geographical area, or complexity. In a larger, more complex campus, the core provides the capacity and scaling capability for the campus as a whole and may house additional services such as security features.

    The question of when a sunder physical core is necessary depends on multiple factors. The capacity of a sunder core to allow the campus network to decipher physical design challenges is important. However, recollect that a key purpose of having a sunder campus core is to provide scalability and to minimize the risk from (and simplify) moves, adds, and changes in the campus network. In general, a network that requires routine configuration changes to the core devices does not yet believe the arrogate degree of design modularization. As the network increases in size or complexity and changes originate to influence the core devices, it often points out design reasons for physically separating the core and distribution functions into different physical devices.

    In brief, although design networks without a core layer may travail at diminutive scale, medium-sized to enterprise-sized networks, they require a core layer for design modularization and scalability.

    In conclusion of the hierarchical model presented in this section, despite its age, the hierarchical model is noiseless apposite to campus network designs. For review, the layers are described as follows:

  • The access layer connects cease devices such as PCs, access points, printers, and so on to the network.
  • The distribution layer has multiple roles, but primarily aggregates the multiple access layers. The distribution may terminate VLANs in Layer 2 to the access layer designs or provide routing downstream to the access layer with Layer 3 to the access layer designs.
  • The next section delves into a major edifice obscure of the campus network: the Cisco switch itself.
