Just share our knowledge for the better future of this world

Okay this is my new knowledge from a course. Packet Tracer 5.0 by Cisco…

Before the course started better know a little about this software and playing a bit with it. Now, i’m gonna make a simple network topology with Packet Tracer 5.0 I’m just create 3 subnets which connected with 2 routers like below

Then we connect each network nodes with connector, oh i forgot… If you want place a network nodes just look at the bottom left of the application window, you’ll find some like this :

After connecting each nodes it will be like this. And the green indicator show the network already connected but if we look at the router there are red light that because we’re not setting it up yet.

How do we set up the routers…?? Click on the router then choose CLI and Check this out configuration for Router0 first

         --- System Configuration Dialog ---

Continue with configuration dialog? [yes/no]: no

Press RETURN to get started!

Router>en
Router#conf t
Enter configuration commands, one per line.  End with CNTL/Z.
Router(config)#interface FastEthernet0/0
Router(config-if)#ip address 10.151.35.1 255.255.255.0
Router(config-if)#no shutdown

%LINK-5-CHANGED: Interface FastEthernet0/0, changed state to up
Router(config-if)#exit
Router(config)#interface FastEthernet0/1
Router(config-if)#ip address 10.151.34.1 255.255.255.0
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
Router(config-if)#exit
Router(config)#
Router(config)#ip route 10.151.36.0 255.255.255.0 10.151.35.2

And then router1

         --- System Configuration Dialog ---

Continue with configuration dialog? [yes/no]: no

Press RETURN to get started!

Router>en
Router#conf t
Enter configuration commands, one per line.  End with CNTL/Z.
Router(config)#interface FastEthernet0/0
Router(config-if)#ip address 10.151.35.2 255.255.255.0
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
Router(config-if)#exit
Router(config)#interface FastEthernet0/1
Router(config-if)#ip address 10.151.36.1 255.255.255.0
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
Router(config-if)#exit
Router(config)#
Router(config)#ip route 10.151.34.0 255.255.255.0 10.151.35.1

And don’t forget to set-up configuration on the PC, just click and choose Config :: Set Settings and FastEthernet

Example for Left

PC : Settings :: Gateway = 10.151.34.1 (just need gateway), then FastEthernet :: IP = 10.151.34.2, Subnet Mask = 255.255.255.0

Okay wait for a few minutes and you’ll see all indicator turn green…. And try to ping like this (from left PC)
