Introduction:
Packet Tracer is a proprietary tool of Cisco. It is used to create &
simulate network virtually. It gives same environment virtually as it
exists physically. So what you do need to do and work same on all
virtually provided devices as you are working with them physically.
This is the beauty of this tool. This tool is widely used in CCNA
training.
This tool gives all type of network devices require to create one real
time working network and also provide same interface as if you are
working on real device.
Packet Tracer WIKI is available. You can read more online about it. Here my focus is how to
use it…

2. Different Operation:
Q1. How to set up instruments?
A1. Click on instrument. Then click on page to drop it.
Q2. How to connect different instruments with cables?
A2. On left bottom cornet you will find sign like
From here you can select your cable
Q3. How to set IP Address in any PC/Laptop or Server?
A3. Select PC in which you want to set IP Address, Click on it. One
menu will open having three tabs: Physical, Config, Desktop.
Select Desktop and go to “IP Configuration”. Here you can set IP
Addresses.
Q4. How to set IP Address in Router?
A4. Select Router , click on it. One menu will open having three tabs:
Physical, Config, CLI.
Select Config.
Select Interface in which you want to set IP, i.e.FastEthernet4/0.
Set IP Address in it & Check the ON check box.

3. Q5. What to do if Router doesn’t have enough Ethernet port to
connect?
A5. In most of the Routers, It has free physical slots which you can fill
up, if you want to connect more devices with Router.
Select Router,
Select tab Physical,
Now on left side there is list of different kind of Ethernet cards
whose detail is given in bottom.
Select the one you want.
Now switch off the Router from the right top side on the picture of
router.
Now Drag the Ethernet card from right bottom most side and drop it
on Routers’ empty slot.
Switch on the Router again.

4. Q6. How to Configure RIP in Router?
A6. In RIP configuration, You just need to enter the network address
of all interface that are directly connected with your Router. In other
word, you need to add all the network addresses which you have
entered in different Ethernet cards in your router.
i.e.
You have Router 1.
You have configured
FastEthernet 4/0 with 192.168.0.1/24
FastEthernet 5/0 with 192.168.1.1/24
FastEthernet 6/0 with 192.168.2.1/24
So for RIP
You need to enter three network addresses
192.168.0.0
192.168.1.0
192.168.2.0

5. 1) One Network(with one PC) One Switch:
Step1: Put one PC & One Generic Switch
Step2: Connect them both with copper straight cable
Step3: Open property of My PC >> Desktop >> IP Configure
Now set following,
IP Address: 192.168.0.1
Subnet Mask: 255.255.255.0
You Are UP!!!!!!!!

6. 2) Two Network(two PC each) One Switch:
Step1: Put four PC & One Generic Switch
PC0 & PC1 for Network 1
PC2 & PC3 for Network 2
Step2: Connect them all with copper straight cable
Step3: Set following IP & Mask
PC Name IP Address Subnet Mask
PC0 192.168.0.1 255.255.255.0
PC1 192.168.0.2 255.255.255.0
PC2 172.16.0.1 255.255.0.0
PC3 172.16.0.2 255.255.0.0

7. Try to ping each other and see what happens…
Observation: Though they are connected with each other with single
switch only PC0&PC1 can communicate with each other and
PC2&PC3 can communicate with each other.
Conclusion: For two computers to communicate, they must be in
same logical network.

8. 3) Two Network Two Switch One Router:
Step1: Put four PC, One Generic Switch & One Generic Router
PC0 & PC1 for Network 1
PC2 & PC3 for Network 2
Step2: Connect them all(Switch & PCs) with copper straight cable
Step3: Connect Switches with Router using Fiber Cable
Step4: Set following IP & Mask
PC Name IP Address Subnet Mask
PC0 192.168.0.2 255.255.255.0
PC1 192.168.0.3 255.255.255.0
PC2 172.16.0.2 255.255.0.0
PC3 172.16.0.3 255.255.0.0

9. Step5: Set the Router’s FastEthernet IP Address in its respective
Interface IP Configuration as follow.
Interface IP Address Subnet Mask
Cable connected with Switch 0 192.168.0.1 255.255.255.0
Cable connected with Switch 1 172.16.0.1 255.255.0.0
Try to ping each other and see what happens…
Observation: Two network 192.168.0.0/24 and 172.16.0.0/16 can
communicate now. We have not specified(applied) any routing
algorithm.
Conclusion: With Router, We can make communication between two
different networks. When different networks are connected with
only one router then they don’t need to use routing algorithm
because router knows the all networks and where to send packets.

10. 4) Two Network Two Switch Two Router:
Step1: Put four PC, One Generic Switch & One Generic Router
PC0 & PC1 for Network 1
PC2 & PC3 for Network 2
Step2: Connect them all(Switch & PCs) with copper straight cables
Step3: Connect Switches with Router using Fiber Cables
Step4: Connect Routers with Fiber Cables
Step5: Set following IP & Mask
PC Name IP Address Subnet Mask
PC0 192.168.0.2 255.255.255.0
PC1 192.168.0.3 255.255.255.0

11. PC2 192.168.1.2 255.255.255.0
PC3 192.168.1.3 255.255.255.0
Step6: Set the Router’s FastEthernet IP Address in its respective
Interface IP Configuration as follow.
Router 0:
Interface IP Address Subnet Mask
Cable connected with Switch 0 192.168.0.1 255.255.255.0
Cable connected with Router 1 172.16.0.1 255.255.255.0
Router 1:
Interface IP Address Subnet Mask
Cable connected with Switch 1 192.168.1.1 255.255.255.0
Cable connected with Router 0 172.16.0.2 255.255.255.0
Step7: Add network address in RIP for routing the packets.
Router 0:
192.168.0.0
172.16.0.0
Router 1:
192.168.1.0
172.16.0.0
Try to ping each other and see what happens…
Observation: Two network 192.168.0.0/24 and 192.168.1.0/24 can
communicate now. We have to configure routing algorithm (In our
case RIP).

12. Conclusion: With Router, We can make communication between two
different networks. When different networks are connected with
more than router then we need to use routing algorithm because
router has to decide where to send packets.

13. 5) Three Network Three Switch Three Router:
Step1: Put six PC, three Generic Switch & three Generic Router
PC0 & PC1 for Network 1
PC2 & PC3 for Network 2
PC4 & PC5 for Network 3
Step2: Connect them all(Switch & PCs) with copper straight cables
Step3: Connect Switches with Router using Fiber Cables
Step4: Connect Routers with Fiber Cables
Step5: Set following IP & Mask
PC Name IP Address Subnet Mask
PC0 192.168.0.2 255.255.255.0
PC1 192.168.0.3 255.255.255.0
PC2 192.168.1.2 255.255.255.0

14. PC3 192.168.1.3 255.255.255.0
PC4 192.168.2.2 255.255.255.0
PC5 192.168.2.3 255.255.255.0
Step6: Set the Router’s FastEthernet IP Address in its respective
Interface IP Configuration as follow.
Router 0:
Interface IP Address Subnet Mask
Cable connected with Switch 0 192.168.0.1 255.255.255.0
Cable connected with Router 1 172.16.0.1 255.255.255.0
Router 1:
Interface IP Address Subnet Mask
Cable connected with Switch 1 192.168.1.1 255.255.255.0
Cable connected with Router 0 172.16.0.2 255.255.255.0
Cable connected with Router 2 172.16.1.1 255.255.255.0
Router 2:
Interface IP Address Subnet Mask
Cable connected with Switch 2 192.168.2.1 255.255.255.0
Cable connected with Router 1 172.16.1.2 255.255.255.0
Step7: Add network address in RIP for routing the packets.
Router 0:
192.168.0.0
172.16.0.0
Router 1:
192.168.1.0
172.16.0.0

15. Router 2:
192.168.2.0
172.16.0.0
Try to ping each other and see what happens…
Observation: Three network 192.168.0.0/24 and 192.168.1.0/24 and
192.168.2.0/24 can communicate now. We have to configure routing
algorithm (In our case RIP).
Conclusion: With Routers, We can make communication between
many different networks.
