CCNA Practice: Router 1720 and TFTP server


1) I have a Cisco Router 1720
2) I can configure this router through a PC
- The PC has a connection to this router through the Console connection
- I can see and edit the "configuration" of the router from the PC
- The Solarwinds TFTP server has been installed in this PC
3)My Goal: I want to practice How to DELETE the IOS or FLASH from this Router and, then install it back to the router
- I heard that we have to use the tftp server
- I heard that we have to provide the IP address to the PC and to the Router(I am still not sure how to provide the IP address to the Router; and how to check it whether it is working)
4) Would somebody provide me the direction for it?
- Configuration of the tftp server?
- how to copy it?
- etc
5) Thank you

You should be able to get the router IP address from a computer connected to it by running the IPCONFIG /all from a command prompt.  Depending upon your network connection it should be the gateway IP address... but not always the case depending upon how your network is using the router. If you can access the configuration of the router you should be able to run the command:  Router# show startup-config
this should show you the router IP address or you can check out the link below for additional info

1) This system is only a Router (Cisco 1720) and a PC
2) I can provide the static IP for the PC, say it :
3) The Router and the PC should be in the same subnet, say it the IP address of the Router is
- The problem is i am still not sure how to give the IP address to the Router
- There is only one ethernet port at the router (What is the name? it is e0/0 or just say it ethernet?)
- So it is correct if i configure the IP address of the router as:
  *Router#config t
  *Router(config)#interface ethernet
  *Router(config-if)#ip address
  *Router(config-if)#no shutdown
  *Router#copy run start
- Is this configuration correct?
- How to test it?
4) Thank you
