Open Tutorial: IS-IS Operations (0.5 days)

Synopsis

IS-IS is a widely used IGP (interior gateway protocol) in both enterprise and service provider networks.

This tutorial will cover how link state protocols work in general, the different IS-IS packet types, IS-IS neighbour discovery, and IS-IS best path selection. We will also discuss best practices around what routing information should be carried in IS-IS.

Target audience

Technical staff who are involved in Internet technology standards, local and national network infrastructure planning & deployment, and day-to-day network operations.

Prerequisites

It is assumed that participants have a basic understanding of:

  • network operations, Internet technologies, OSI reference model and TCP/IP.
  • Basic Linux command line (CLI) skills.
  • The lab exercises use Cisco IOS configuration syntax.

We recommend the following Academy courses be completed before the start of the tutorial:

Other requirements

  • Hardware: It is highly recommended that participants bring their own laptop computers with Wifi(b/g/n) and administrative access to system to practice the lessons learned during the workshops.
  • Software: SSH Client, Telnet Client (PuTTy)
  • Confirm Secure SHell (SSH) is allowed from the office or home network to access the lab infrastructure? Test ssh connectivity, try to connect to route-views.routeviews.org. For example from the CLI type: ssh [email protected]
  • Attendees must have an APNIC Academy login account. If you don’t have one already, you can create an account for free at https://academy.apnic.net/
  • Please test the speed of your Internet connection to the servers where the Virtual Machines (VMs) are hosted at the Learn on Demand data centres, using the speed test tool at https://www.learnondemandsystems.com/speedtest/
