## Introduction

This lab runs on a virtualised environment for Cisco IOS called “CSR1000v” for the core, border, access and peering routers, “IOSv” for the customer, trigger, and IXP services routers, and “IOSvL2” for the IXP switches.

The method of access to each virtual router or switch is via a web interface on the system that runs the virtualization platform.

## Lab access instructions

The instructors will divide the class into groups, where each group is responsible for the operation of an autonomous system. Decide amongst yourselves which person will be responsible for configuring each device in your group.

Access to the consoles is via a web interface at `http://vtp.ws.nsrc.org/` or at the URL noted by the workshop instructors.

This lists all the groups and drop down menus for each group listing all the available devices in each group. Click on the device whose console you want to use. Please don’t connect to devices in other groups!

## Login Instructions

Once connected, hit Return a couple of times and you should get the prompt for the chosen device. If it does not respond, even after hitting the Return key several times, please request help from the workshop instructors.

Then, if you see this question:

    Would you like to enter the initial configuration dialog? [yes/no]:

Answer “no”.

The router will show some initialization routines, and finally, you will see the default prompt:

    Router>

You can then go into privileged mode:

    Router> enable
    Router#

And then enter configuration mode:

    Router# configure terminal
    Router(config)#

And you are ready to start entering configuration statements. When you are done, exit configuration mode by typing end or pressing ctrl-Z and save your changes:

    Router(config)# end
    Router# write memory
