I have a huge running config in a 7206vxr router (15,000 line long for the TN3270-server PU/LU config.) The startup-config is very basic with just enough commands to boot up and then it does a "boot network ftp......." to get the full running config.
I want to make a change to the basic startup config, but if I go into 'config t', make the change and then do a 'wr' then the router attempts to copy the huge running-config to the startup-config - and it is so big it gives me warning messages and fails .
So how can I make a change to the basic startup-config?
