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.

$ telnet <HOST-IP> <PORT>

For example:

$ telnet 10.10.0.241 2012

The instructor will provide the IP address of the host in this particular workshop

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 "R32" (ID 8, type c7200) - Console port

Hit ENTER at this point. Then, you will 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 and save your changes:

Router(config)# end
Router# write memory
