Interconnecting Network Devices

Exam 604 802 (CCNA)

Interconnecting Cisco Networking Devices focuses on providing the skills and knowledge necessary to implement and support a small switched and routed network. For the purpose of this course, a small network is defined as 1 to 20 hosts connected to a single switch, with the switch running a single VLAN (VLAN1). The switch is also connected to a router providing a routed link (Routing Information Protocol [RIP] and default) to a simulated Internet and corporate office. ICND1 works from the bottom up, providing knowledge and skills as they are needed.

The course starts with an introduction to networks. It then introduces host-to-host communications using TCP / IP. Next, Layer 2 devices (switches) are introduced into the network. Next, Layer 3 devices (routers) are introduced into the network. The introduction of Layer 3 devices leads to the use of WANs and routing to connect the site to the Internet and corporate sites.

The course also focuses on using Cisco catalyst switches and Cisco routers that are connected in LANs and WANs typically found at medium-sized network sites. Upon completing this training course, you should be able to configure, verify and troubleshoot the various Cisco networking devices in a small network environment.

Course Benefits

Upon completing this course, the learner will be able to meet these overall objectives:

  • Describe how networks function, identifying major components, function of network components, and the OSI reference model
  • Using the host-to-host packet delivery process, describe issues related to increasing traffic on an Ethernet LAN and identify switched LAN technology solutions to Ethernet networking issues
  • Describe the reasons for extending the reach of a LAN and the methods that can be used, with a focus on RF wireless access
  • Describe the reasons for connecting networks with routers and how routed networks transmit data through networks using TCP / IP
  • Describe the function of WANs, the major devices of WANs, and configure PPP encapsulation, static and dynamic routing, PAT, and RIP routing
  • Use the command-line interface to discover neighbors on the network and manage the router start up and configuration
  • How to configure and troubleshoot a small network
  • Expand the switched network from a small LAN to a medium-sized LAN with multiple switches, supporting VLANs, trunking, and spanning tree.
  • Describe routing concepts as they apply to medium-sized network and discuss considerations when implementing routing on the network
  • Configure verify and troubleshoot EIGRP
  • Determine how to apply ACLs based on network requirements, and to configure, verify and troubleshoot ACLs on a medium-sized network
  • Describe when to use NAT or PAT on a medium-sized network and configure NAT or PAT on routers
  • Identify and implement the appropriate WAN technology based on a network requirements
