What determines how large your config file can be? Is it the size of NVRAM on the router?

    the config file will vary in size depending on how much stuff you have configured...

    Basically yes. It really shouldn't be a problem but if you did run out of NVRAM, you could load a config from tftp into RAM.

    Would it be a wise idea to load every router in an institute from saved config files on a TFTP server?

    I don't think that's necessary... but backed up to a tftp server is always a good idea.

    If all devices booted from the tftp server, and the server went down... dayum, you're toast. Same with network connectivity issues.
    There are only 10 kinds of people... those who understand binary, and those that don't.

    Not really,for a number of reasons. What happens if there is no connectivity when trying to obtain the config from the tftp server? TFTP is not a secure protocol so anyone could read the clear text config sent across the network. There's a few others. We used this method for pur customer routers that were located at the customer sites because we didn't want them to be able to preform password recovery and get any sensitive config information.

    I understand. Thanks!!!!

    If you did a show ver or show hardware, the amt of memory showing for NVRAM would be the limit for how big your config could be, correct?
