ICND2 v2.0 – Interconnecting Cisco Networking Devices

Interconnecting Cisco Networking Devices, Part 2 (ICND2) v2.0 is a instructor-led training course that teaches learners how to install, operate, configure, and verify a basic IPv4 and IPv6 network, including configuring a LAN switch, configuring an IP router, connecting to a WAN, and identifying basic security threats.

ICND2 v2.0 focuses on understanding redundant topologies, troubleshooting common networking issues, configuring EIGRP and multiarea OSPF in both IPv4 and IPv6, understanding WAN technologies, and becoming familiar with device management and Cisco licensing. The learner will encounter more troubleshooting and more lab time than with the previous version of ICND2.


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

  • Operate a medium-sized LAN with multiple switches, supporting VLANs, trunking, and spanning tree
  • Troubleshoot IP connectivity
  • Configure and troubleshoot EIGRP in an IPv4 environment, and configure EIGRP for IPv6
  • Configure and troubleshoot OSPF in an IPv4 environment, and configure OSPF for IPv6
  • Define characteristics, functions, and components of a WAN
  • Describe SNMP, syslog, and NetFlow, and manage Cisco device configurations, Cisco IOS images, and licenses


The knowledge and skills that a learner must have before attending this course are as follows:

  • Understand network fundamentals
  • Implement local area networks
  • Implement Internet connectivity
  • Manage network device security
  • Implement WAN connectivity
  • Implement basic IPv6 connectivity


  • Target Candidate: Individuals seeking the Cisco CCNA Routing and Switching certification. The course is also appropriate for pre-sales and post-sales network engineers involved in the installation and support of enterprise branch office networks.
  • Key Job Tasks:
    • Configure: Implement the identified solution by applying the planned implementation processes using Cisco IOS commands and applications in the correct order to the selected devices and portions of the network.
    • Verify: Use the appropriate show and debug commands and applications to ensure that the solution was correctly implemented and is performing as desired.
  • Job roles: Entry Level Network Engineer, Network Administrator, Network Support Technician, and/or Help Desk Technician.
