Lab Access

Introduction

This lab runs on a virtualised environment for Cisco IOS called "Dynamips". The method of access to each virtual router is via Telnet to a specific port on the IP of the machine that runs the virtualization platform.

For example:

$ telnet vtp.ws.nsrc.org 2012  

The instructor will confirm the name or IP address of the host in this particular workshop.

Dynamips Port to Router Console Map

The routers in each group are accessed as follows:

The instructors run the other routers in the lab topology - these are accessed by them using these port mappings:

Login instructions

After executing the telnet command, you will see something like the following:

Trying 10.10.0.241...
Connected to 10.10.0.241. 
Escape character is '^]'. 
Connected to Dynamips VM "C5" (ID 8, type c7200) - Console port

Hit ENTER at this point. 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

If you see the following message appear in the router’s initialisation routines, there is no need to worry about it. It applies only in the case of physical hardware (indicating that the combined interface bandwidth is greater than that supported on the internal bus), and not to our virtual environment.

WARNING: PCI bus mb0_mb1 Exceeds 600 bandwidth points
WARNING: PCI bus mb2 Exceeds 600 bandwidth points
