Interconnecting Cisco Network Devices (ICND) Intermediate
5 Days

This hands-on course provides a technical foundation to familiarize the student with Cisco technology or to become a Cisco Certified Network Associate. The course delivers essential information needed to pass CCNA certification, and also includes comprehensive hands-on reinforcement to ensure that you add skills and not just knowledge. If you are new to Cisco, ICND prepares you for the tasks you will face on the job.

GOALS—Upon completion of this class you will:
  • Interpret and create IP subnet masks
  • Interconnect networks using TCP/IP
  • Avoid redundant switching
  • Configure VLANs
  • Understand the function of spanning tree algorithms
  • Understand, code and test vector routing protocols
  • Understand the advantages/disadvantages of Link state routing protocols
  • Learn about and configure RIP
  • Learn how IGRP operates; Compare IGRP to EIGRP
  • Learn how to use VLSM
  • Explain how access lists can be configured on a router
  • Explain how NAT and PAT are configured
  • Understand how to configure a router for Point-to-point serial encapsulation
  • Configure PPP, CHAP, and PAP
  • Build WAN links using Frame Relay
  • Be able to explain the differences between ISDN’s BRI and PRI
  • Configure DDR across ISDN BRI

AUDIENCE is for those who have a firm background in data networking and are looking to achieve the first level of Cisco certification, the CCNA. Students without this background should first attend a TCP/IP Introduction class or an ICRC class.
