What The CCNA
607 Router Simulator Contains
The CCNA
607 Router Simulator contains the following devices for you to configure and
interact with:
 Five (5) Cisco 25001 routers with Enterprise edition 12.09 software. The 2501’s have
one Ethernet and two Serial interfaces
 Four (4) hubs.
 One (1) Cisco Catalyst 1900 switch with Enterprise edition software. The 1900 switch
has twelve 10BaseT switched ports and two FastEthernet switched ports.
 Ten (10) hosts.
Our Internet Authorization is Easy to Implement!
As long as you are connected to the Internet it takes only seconds to become authorized to
use the program. We supply you with a product ID sticker on the CD jewel case. When
prompted you will enter the product ID. If it is a legitimate product ID, you will be ready to go
within seconds.
What If I Do Not Have Internet Access?
You can still use our program! As you go through the procedure to install authorization, you
can call our technical support department to exchange some numbers and within minutes you
will be up and running.

Learning with the CCNA

607 Router Simulator

This product was mainly developed to be an instructional tool that you can use to learn how to
configure a network. You start out reading about basic commands and proceed to more
advanced topics in the labs. Along the way, you can put into practice what you read. As you
interact with the simulator, you will learn what commands are appropriate at each mode, plus,
the effects they have on the configuration of your network.

You learn by doing. You learn by interacting with a network in a safe environment. You do
not have to worry about bringing a network down and affecting others. This is your
customized network that you build in any way that you want. You can start over if you want,
by removing any configuration(s) that you desire, one command at a time, or by entering
erase start and reload on routers, and delete nvram on the 1900 switches.


11
Finally, people learn best when they can practice with realistic situations that model their real
working environment. It is then easier for someone learning about routers to transfer
knowledge from an instructional setting to their real working environment.

Removing the CCNA
607 Router Simulator From the Network Server

If you want to remove the CCNA 607 Router Simulator and all associated files from your
network server...

1. Remove your licenses
before you remove the CCNA 607 Router Simulator program.
2. On your network server, go to the RouterSim\CCNA607 directory.
3. Find the file labeled “Unwise.exe”.
4. Double-click the program.
5. Follow the prompts in the uninstall program



18
Important Information About Your Authorization

Authorization Location


Authorization is placed in a subdirectory under your RouterSim\CCNA607 directory in
a directory called “ax nf zz”. Do not delete, move, or tamper with this directory; you
could lose your authorization.

Formatting Your Hard Drive

Remove the authorization from your hard drive before you re-format your hard drive.
If you do not, you will lose the authorization placed on your hard drive. After
formatting is complete, re-install the authorization from the main menu in your
program.

Installing or Removing Your License

Only install and remove authorization from the CCNA 607 Router Simulator
program. Use the buttons on the main menu of our product to install and remove

your license. If you want to uninstall your CCNA 607 Router Simulator program,
always remove your authorization first.

If You Use Hard Disk Maintenance Utilities


If you use Norton Speed Disk or Diskeeper, they may not recognize our authorization
file (ccna607.ekb). If possible, it is extremely important to enter .ekb as an
unmovable extension in the properties section of your software utility. An example
would be entering the path: “c:\routersim\CCNA607\ax nf zz\ccna607.ekb”.

If this is not done, your authorization program (ccna607.ekb) may become corrupted
when you run such a utility and you will lose your authorization on your hard disk.
You also have the option of removing your authorization before running such a utility.

Corrupted Authorization


If you try to copy, move, or tamper with the authorization on your hard drive, it will
become corrupted and you will lose an authorization. The only acceptable way of
interacting with the authorization is to install and remove it from our program.


19
Ghosting


You will run into problems if you ghost your computer without first removing our
authorization. Remove our authorization back onto the authorization diskette before
you ghost your computer. The reason for this is because with ghosting you could

potentially produce unlimited copies of our authorization. However, this will not work.

If You Have Problems With Our Authorization


If you have a problem with the authorization and cannot proceed beyond the main
menu, please email us at We will work with you
and your problem. However, if you follow the guidelines described in this section,
you more than likely will have no problems.



20
Authorization Error Codes:

You may encounter an error code when you try to install your license(s) or run the program.
The following information will assist you understanding and trying to figure out the source of
the problem. If you have a problem that you cannot solve, you can contact our Technical
Support Department at RouterSim.

Code Description

0 Your authorization file cannot be found. An error 0 can occur during
verification of authorization when you try to go to the Network Visualizer
screen from the main menu. Authorization was not found on your hard drive
during verification. Either authorization has not been placed on the hard
drive, it has been removed, or it has become corrupted. The likely cause of
corruption is that a utility such as Norton Speed Disk has been run.

1 An invalid activation code has been entered.

2 An authorization has already been activated on your computer.
3 This code can occur if the authorization on your hard drive has been
corrupted. This can occur if it is tampered with or corrupted by another
program such as a hard disk utility.
14 Database authorization file not found - An invalid product ID number was
entered.
15 Database authorization file not found - An invalid product ID number was
entered.
19 This code can occur if the authorization has not been activated on your hard
drive. It actually exists on your hard drive, but in inactive form. You must be
sure to activate the authorization in order to use the product.
21 Database authorization file not found - An invalid product ID number was
entered.
35 An invalid product ID code was entered. Try again.
37 You are trying to remove an authorization from your hard drive but the
program cannot find an activated file.
52 There are no more authorizations left to activate. The program comes with
one license.
251 Connection to the server where you activated your authorization failed.
Please try again.
252 Please check your Internet connection. You need to be connected to the
Internet before you install or uninstall authorization.

Starting the CCNA
607 Router Simulator

After you have installed your license onto your hard drive, click the button that says
“Continue”. If you have a legitimate license on your computer, you will see our main screen

within a few seconds.

Network Visualizer Screen

One of the main screens in the program is the Network Visualizer screen. On this screen
you see a graphical layout of your static network. The other main screen is a simulation
screen where you enter all your configuration commands. If you want to configure a
specific router or switch, double-click the graphic that represents that device.







23
Net Configs


As you configure your network you will want to look up configurations for the different
devices. Click the button at the top of the screen that says “Net Configs”. You can click
on any device name to go to the simulation screen for that device. You can also lookup
passwords that you have forgotten by viewing the Net Configs screen.

Program Options

Display Lab Window

You can display a lab below the simulation screen or in a separate, pop-up dialog box.
We give you this option because you may want to move your lab dialog box below the
simulator field.

Location of Configuration File

By default your configuration file is saved to your application directory. You may,
however, also save your configuration file to a diskette.




25
Simulation Screen

The other main screen in the program is the simulation screen. This is where you enter
your configurations for the different devices. To go to a simulation screen, on the
Network Visualizer screen, double-click on a device such as a 2501 router or 1900
switch.
