Hi Emil,
On TFTP server you can use alias for the IOS without having to actually
rename the IOS on flash. TFTP clients will see that IOS with the alias name.
On your R4 routers, you should do something like:
R4(config)#tftp-server flash:c1841-ipbasek9-mz.124-15.T1.bin alias
cisco2-c1841
On the other router, that needs to download IOS via TFTP from R4, you can
try and see if in fact you can download it without having to copy it to
flash using "copy tftp null" command. Of course, if that router is already
in ROMOM mode, you wont be able to test that command, but you can just have
your fingers crossed, and simply reload it and see if it picks up new IOS
after the reload.
R1#copy tftp: null:
Address or name of remote host []? 10.0.1.4
Source filename []? cisco2-c1841
Accessing tftp://10.0.1.4/cisco2-c1841...
Loading cisco2-c1841 from 10.0.1.4 (via FastEthernet0/1.1):
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Cheers,
Huan

Hi Tony,
Eventhough I received the warning message, the command was actually accepted
(see below).
R4#sh run | s tftp
tftp-server flash:cisco2-c1841
Do I really need to copy & rename an IOS image to cisco2-c1841 to fully meet
the task requirement?
Can you kindly clarify: Is "cisco2-c1841" the default IOS image that the
router will boot via TFTP as per the outputs of "confreg"?
Thank you.
BR,
Emil
