Does anyone know how to upgrade the IOS of one router from another router. Can this be done by a Serial connection or is an Ethernet connection needed? Any link or info would be great.
In my opinion, without using any books, if you have the two routers connected in a valid network, it should work. Since you can make this network both using Serial or Ethernet ports, I think that the network can be done.
Step 2: since it seems that a router can be both a TFTP client and server (I have no idea yet how to make it a TFTP server) it seems that you have now the place to store the IOS. However, how do you place the required IOS file on this TFTP server/ router without a host (PC)? I do not know.
Step 3: if you succeeded to load the IOS file on the server (TFTP server router) you can upgrade by using “copy tftp flash” command.
I hope I’ve gave good indications, but I’ll be also interested to find out if I was wrong!
Ok i have done this. Here is what you need to do
step 1: download a tftp server software (download.com)
step 2: setup an ethernet connection between the computer running the tftp server and the router. Send the ios image to the tftp server
step 3: change the ethernet to computer to router with old or no IOS.
step 4: copy tftp flash
step 5: you have to type in the ios image name all the time ( i dont remeber the exact syntex, its been a while, sorry)
