CIS 2421 Scaling Networks

The focus of this course 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. Students will be able to configure and troubleshoot routing protocols and wireless networks using IPv4 and IPv6 on equipment from various vendors.

Prereqs: CIS 2416  CIS 2416 must be completed within the past two years. 


  • Design, build, and configure hierarchical networks with appropriate hardware using a IOS.
  • Describe and explain the use of naming and licensing of IOS images in networking equipment. Configure, install and upgrade an IOS image to a piece of networking equipment.
  • Describe enhanced switching technologies such as VLAN Trunking Protocol (VTP), Rapid Spanning Tree Protocol (RSTP) and IEEE 802.1q frame tagging. Troubleshoot STP implementation, ether channel, and link aggregation. Describe and understand the use of VOIP on the network and configure and manage a VOIP network with the use communication management software.
  • Describe how a router determines path information through advanced router configurations (OSPF). Use the command line interface (CLI) to investigate routing tables and troubleshoot network problems. Configure advanced classless routing. Configure and verify advanced configurations in the routing table and other database tables. Understand and configure other vendor equipment through CLI for basic configurations, secondary system configuration, policies, filters, and firewall.
  • Configure, troubleshoot and verify basic EIGRP and apply advanced configuration, verification, and troubleshooting commands with routers implementing EIGRPv4 and EIGRPv6. Design an IP addressing scheme and use advanced configuration commands to implement Enhanced Interior Gateway Protocol (EIGRPv4 and EIGRPv6). Use router show and debug commands to troubleshoot common errors that occur on small to medium routed networks.
  • Identify basic configuration parameters on a wireless network to insure connectivity. Configure a wireless NIC, access point and wireless router. Select the appropriate security protocols to mitigate threats to wireless LANs. Use a systematic approach to wireless LANs troubleshooting to solve access point and firmware issues.
