IS-IS Operation

Date: 15th February 2022
Venue: Online

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 folks who are building or operating a service provider or enterprise network.

Pre-requisites

It is assumed that participants have a 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:

• Routing Basics: https://academy.apnic.net/en/course/routing-fundamentals-course/
• Linux Basics virtual lab: https://academy.apnic.net/en/virtual-labs/

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 rviews@route-views.routeviews.org
