The focus of this module is on the architecture, components, and operations of routers and switches in a larger and more complex network. Students will learn how to configure routers and switches for advanced functionality. Learners will: Configure and troubleshoot DHCP and DNS operations for IPv4 and IPv6. Describe the operations and benefits of the Spanning Tree Protocol (STP).Configure and troubleshoot STP operations.Describe the operations and benefits of link aggregation and Cisco VLAN Trunk Protocol (VTP).Configure and troubleshoot VTP, STP, and RSTP.Configure and troubleshoot basic operations of routers in a complex routed network for IPv4 and IPv6.Configure and troubleshoot advanced operations of routers and implement RIP, OSPF, and EIGRP routing protocols for IPv4 and IPv6.Manage Cisco IOS® Software licensing and configuration filesBy the end of this course, students will be able to configure and troubleshoot routers and switches and resolve common issues with OSPF, EIGRP, STP, and VTP in both IPv4 and IPv6 networks. The learner will also develop the knowledge and skills needed to implement DHCP and DNS operations in a network.
Introduction to Scaling Networks
This topic 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. The goals of network design are to limit the number of devices impacted by the failure of a single network device, provide a plan and path for growth, and create a reliable network.
LAN Redundancy
This topic focuses on the protocols used to manage these forms of redundancy. It also covers some of the potential redundancy problems and their symptoms.
Link Aggregation
Link aggregation is the ability to create one logical link using multiple physical links between two devices. This chapter describes EtherChannel and the methods used to create an EtherChannel. An EtherChannel can be manually configured or can be negotiated by using the Cisco-proprietary protocol Port Aggregation Protocol (PAgP) or the IEEE 802.3ad-defined protocol Link Aggregation Control Protocol (LACP).
Wireless LANs
Wireless networks can provide client mobility, the ability to connect from any location and at any time, and the ability to roam while staying connected.This chapter covers WLAN technology, components, security, planning, implementation, and troubleshooting. The types of network attacks to which wireless networks are particularly susceptible are discussed.
Single Area OSPF
OSPF is a popular link state routing protocol that can be fine-tuned in many ways.This chapter of OSPF describes these tuning features, the configuration mode commands to implement these features for both IPv4 and IPv6, and the components and commands used to troubleshoot OSPFv2 and OSPFv3.
Multiarea OSPF
Multiarea OSPF is used to divide a large OSPF network. Too many routers in one area increase the load on the CPU and create a large link-state database. Discussion is focused on the LSAs exchanged between areas. In addition, activities for configuring OSPFv2 and OSPFv3 are provided.
EIGRP
Enhanced Interior Gateway Routing Protocol (EIGRP) is an advanced distance vector routing protocol developed by Cisco Systems. This chapter introduces EIGRP and provides basic configuration commands to enable it on a Cisco IOS router. It also explores the operation of the routing protocol and provides more detail on how EIGRP determines best path.
EIGRP Advanced Configurations and Troubleshooting
EIGRP is a versatile routing protocol that can be fine-tuned in many ways. This chapter discusses these additional tuning features and the configuration mode commands to implement these features for both IPv4 and IPv6
IOS Images and Licensing
Cisco IOS (originally Internetwork Operating System) is software used on most Cisco routers and switches. IOS is a package of routing, switching, security, and other internetworking technologies integrated into a single multitasking operating system. This chapter discusses the process of obtaining, installing, and managing Cisco IOS 15 software licenses.
Hierarchical Design and Connecting to the WAN
Introduces network design concepts, principles, models, and architectures. It covers the benefits that are obtained by using a systematic design approach. Emerging technology trends that will affect network evolution are also discussed.Different technologies are used for WANs than for LANs. This chapter introduces WAN standards, technologies, and purposes. It covers selecting the appropriate WAN technologies, services, and devices to meet the changing business requirements of an evolving enterprise.
PPP snd Frame Relay
HDLC and Point-to-Point Protocols (PPP) are introduced. PPP is a protocol that is able to handle authentication, compression, error detection, monitor link quality, and logically bundles multiple serial connections together to share the load. Frame Relay is a high-performance WAN protocol that operates at the physical and data link layers of the OSI reference model.
NAT for IPv4 and Broadband Solutions
The chapter discusses how NAT, combined with the use of private address space, is used to both conserve and more efficiently use IPv4 addresses to provide networks of all sizes access to the Internet.This chapter covers commonly used broadband solutions, such as cable, DSL, and wireless. VPN technology provides security options for data running over these connections
Securing the Site and Monitoring the Network
This chapter explains the concepts and processes related to VPNs, as well as the benefits of VPN implementations and the underlying protocols required to configure VPNs.This chapter covers three protocols that a network administrator can use to monitor the network. Syslog, SNMP, and NetFlow are popular protocols with different strengths and weaknesses.
Troubleshooting the Network
This chapter describes the network documentation that should be maintained and general troubleshooting procedures, methods, and tools. Typical symptoms and causes at several layers of the OSI model are also discussed. This chapter also includes some information about troubleshooting path and ACL issues.
