Course overview

This course examines the operation and use of the standards-based Intermediate System-to-Intermediate System (IS-IS) routing protocol. The course begins with a review of IP routing and the different methods available to populate the routing table. It briefly covers static routing and covers the IS-IS routing protocol in detail. It also covers concepts such as route redistribution, route filtering, equal-cost multipath (ECMP) routing, bidirectional forwarding detection (BFD), and IP fast re-route based on loop-free alternative (LFA) paths. Configuration of both IPv4 and IPv6 routing is included. All use cases and lab exercises are based on the model-driven command-line interface (MD-CLI). Upon completion of this course, students will be able to explain the operation of IS-IS and be able to configure and verify complex networks using the IS-IS protocol.

Course objectives

After completing the course, students should be able to:

  • Describe the Internet Protocol (IP) addressing and forwarding process
  • Explain the difference between static routing and dynamic routing protocols
  • Identify common interior and exterior routing protocols
  • Describe the benefits of equal-cost multipath routing (ECMP)
  • Describe route redistribution and route filtering
  • Explain the main characteristics of link state routing protocols
  • Explain the messages, adjacency states, and link state advertisements of IS-IS
  • List the steps required to configure IS-IS for IPv4 and IPv6

Prerequisites

It is strongly recommended to have completed the Nokia IP Networks and Services Fundamentals course. Alternatively, it is recommended to have working knowledge of Ethernet and IP routing, and familiarity with the model-driven command-line interface of the service router operating system (SR OS MD-CLI).
