Configuring Routers and Pc`s in Packet Tracer

 
Before you start this tutorial you will need to download Packet Tracer here:

Objective         : To give you a realistic idea on configuring a cisco router and networking it within
                          a network enviroment.
Skill Set           :A working brain.
Difficulty          :Easy
Virtual Tools    :Cisco packet tracer, Cisco router, two switches, four desktop machines.
For Whom      : My networking buddies.


                                          Configuration Start [59] - Subnet 1

Step 1 - Enter commands at the command line interface (CLI) of the router.

1.Click on router -> Click CLI  Tab

2.You will be greeted with (Continue with configuration dialog?) type no
3.Type enable and press enter
3.Type config t and press enter
4.Type interface fastethernet 0/0 and press enter
5.Type in the ip address followed by the subnet mask then press enter
6.Type no shutdown (Your link should light up)
7.Type Enter
7.See below what it should look like at the CLI (Command Line Interface) configuration:

\\
Continue with configuration dialog? [yes/no]: no
Router>enable
Router#config t
Enter configuration commands, one per line.  End with CNTL/Z.
Router(config)#interface fast
Router(config)#interface fastEthernet 0/0
Router(config-if)#ip address 192.168.1.1 255.255.255.0
Router(config-if)#no shutdown

%LINK-5-CHANGED: Interface FastEthernet0/0, changed state to up
%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/0, changed state to up
\\

The first Fast Ethernet (0/0) link should be up and blinking.


Step 2 - Configure the ip address for the two pcs on Fast Ethernet 0/0 (First Subnet).


1.Double click on the first Pc (Pc0) and click on the Desktop Tab.
2.Click on Ip Configuration->Static
3.Set the Ip Address as follows:
   -IP Address         :192.168.1.2
   -Subnet Mask      :255.255.255.0
   -Default Gateway  :192.168.1.1

Step 3 - Ping the router to make sure you can get connectivity.


1.Double click on the first Pc and click on the Desktop Tab
2.Click on Command Prompt
3.From the Command Prompt type ping 192.168.1.1
4.You should get replies which means that your Pc can communicate with the router successfully.
5.Close the Command Prompt

 Step 4 - Configure the ip address for the second pc (Pc1) on Fast Ethernet 0/0

1.Double click on the first Pc and click on the Desktop Tab (same as step 2).
2.Click on Ip Configuration->Static
3.Set the Ip Address as follows:
   -IP Address       :192.168.1.3
   -Subnet Mask      :255.255.255.0
   -Default Gateway  :192.168.1.1

Step 5 - Checking to see if your network on Fast Ethernet 0/0 is working.You will ping Pc0 from Pc1.

1.Double click on the second Pc (Pc1) and click on the Desktop Tab
2.Click on Command Prompt
3.From the Command Prompt type ping 192.168.1.2 (Pc 0)
4.You should get replies which means that your Pc can ping Pc0 successfully.
5.Close the Command Prompt
6.Congratulations your network on subnet 1 (192.168.1.1) is working properly.

                                Configuration restarts [59] - Subnet 2

 Step 1 - Configure Fast Ethernet 0/1 on Router 0 on the second Subnet (192.168.2.1)

1.Double click on the router
2.Click on the CLI Tab
3.Do same as in step 1 on Fast Ethernet 0/0 on subnet 1 only difference is ip address will be 192.168.2.1
4.Please see below :

Router>enable
Router#config t
Enter configuration commands, one per line.  End with CNTL/Z.
Router(config)#interface fastEthernet 0/1
Router(config-if)#ip address 192.168.2.1 255.255.255.0
Router(config-if)#no shutdown

%LINK-5-CHANGED: Interface FastEthernet0/1, changed state to up
%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/1, changed state to up


5.Your Fast Ethernet 0/1 (192.168.2.1) should be blinking green, indicating that your link is up.




Step 2 - You need to configure the Pcs for Fast Ethernet 0/1 on subnet 192.168.2.1

1.Double click on the first Pc (Pc2) and click on the Desktop Tab.

2.Click on Ip Configuration->Static
3.Set the Ip Address as follows:
   -IP Address       :192.168.2.2
   -Subnet Mask      :255.255.255.0
   -Default Gateway  :192.168.1.1

Step 3 -  Ping the router from Pc2 on Fast Ethernet 0/1 to make sure you can get connectivity.

1.Double click on the Pc2 and click on the Desktop Tab
2.Click on Command Prompt
3.From the Command Prompt type ping 192.168.2.1



4.You should get replies which means that your Pc can connect to the router Successfully.
5.Close the Command Prompt

Step 4 - You need to configure Pc3 ip address on Fast Ethernet 0/1 for subnet 192.168.2.1 .

1.Double click on the second Pc(Pc3) and click on the Desktop Tab.
2.Click on ip configuration->Static
3.Set the Ip Address as follows:
   -IP Address       :192.168.2.3
   -Subnet Mask      :255.255.255.0
   -Default Gateway  :192.168.1.1

Step 5 - Checking to see if your network on Fast Ethernet 0/1 is working.You will ping Pc2 from Pc3.

 1.Double click on the second Pc (Pc3) and click on the Desktop Tab
 2.Click on Command Prompt
 3.From the Command Prompt type ping 192.168.2.2
 4.You should get replies which means that your Pc can ping Pc2 successfully.
 5.Close the Command Prompt
 6.Congratulations your network on subnet 2 (192.168.2.1) is working properly.

Step 6 - Testing connectivity from subnet 192.168.1.1 through subnet 192.168.2.1

1.From Pc0 open up a command prompt
2.Ping 192.168.2.2
3.Once you get replies with all packets received, you network is working from subnet 1
4.From Pc3 open up a command prompt
5.Type ping 192.168.1.2
6.Once you get replies with all packets received, your network is working from subnet 2
7.Congratulations your network is working, period!!!
