We will router's configuration in gns3 and also the usage of VPCS(virtual client nodes or computers). To start with we will open a new project in gns3.
1. Drag a c3600 router on workspace.
2. Now Drag a VPCS (virtual host) on the workspace just like you dragged the router
3. Now we have to connect this pc with router. To connect pc with router click on link icon from left
then click on pc and select ethernet and do the same for router to see router and pc joined via a link. Make sure an ethernet slot is added to the router already
4. To start the router right click on the router and select start.
5. Once the router starts successfully, We can try different configurations or start practicing. To configure a router in gns3, Right click on the router and select console
6. When PC and router both are started, We need to assign ip addresses to both devices for them to be able to communicate with each other. We will end this tutorials on successfull ping test. Now right click the PC and select console

7. Now enter "show" to see current ip address of this node
8. You can assign ip address to this node by using command ip (address) (subnet mask) (gateway address)
9. Let us assign ip address to our router's ethernet interface(which is connected to PC). open router's console,
10. There are three modes of a router. User EXEX Mode, Priviliged EXEC Mode, Global Configuration Mode. Most of router's configuration is done in global configuration mode.
11. A router usually starts in USER EXEC MODE. To goto priviliged exec mode enter enable. to goto global configuration mode press config terminal in priviliged EXEC Mode. Let's goto global config mode.
12. Let's assign ip address to our router's interface. First we will have to goto that particular interface which we want to configure. To do that we need to know it's interface name or number. We can make gns3 show nodes interface labels as shown in figure below
13. As we can see it's e3/0. We can make the router show it's interfaces by using command do show ip interface as shown in figure below
14. Let's move to interface ethernet 3/0, assign ip address and make sure it's not shut down as shown below
15. Let us test if PC can communicate with router or not. It's successful, yayyy.. In next tutorial we will study some basic configuration of the router

ReplyDeleteThat is packet tracer. After connecting routers with serial cable, you have to configure the serial interfaces of routers to establish communication.
