Overview

This 3 day lecture course on Internetworking will give an overview of the major topics important when building products used to form IP infrastructures and to interface to the Internet. The course therefore has a bias toward network product developers. The course can be extended to 5 days if delegates wish to include 'hands on' exercises and labs.

Objectives

When attendees have completed this course they will have learned how to:

  • Use the correct technical terms and key technology models to describe Internetworks
  • Identify the latest LAN technologies, interfaces and VLAN standards
  • Interconnect networks at OSI layer 2 using IEEE 802.1d and layer 3 using IP
  • Describe the key Internet routing and addressing functions
  • Compare and contrast the function of the key routing protocols, in particular OSPF and BGP4
  • Describe how MPLS and IEEE 802.1p/q can be deployed to deliver Quality of Service
  • Select the most appropriate routing protocols for application interfaces on the Internet
  • Identify how virtual private networks can be built using typical technologies
