Nokia IS-IS Routing Protocol

Course number: OP00060
Course duration: 3 days
Price: €2,400

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.

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).
