"bootfile" is actually an older term (re: the RFC) that referred to a startup file back in the days when hosts truly were dumb in that they had only ROM-based information for bootup and had to learn everything else.
>From a router's perspective where IOS is quite a bit brainier than older devices, that bootfile simply tells it how to behave. All IOS needs to know how to behave is what we refer to as the config file. So it is correct. Bootfile specifies the filename to look for and option 150 specifies the TFTP server to grab it from.

In one of the practice labs that I have, there is an "IOS" question requesting to set up DHCP on a router to not only provide an ip address to a future new router (AutoConfig), but also to point this new router to a TFTP Server that holds a configuration file called "R9-config. After a while trying to figure out the answer without success, I checked the book looking for the correct config. According to the book, the answer is: ip dhcp excluded-address 10.50.50.1 10.50.50.5 ! ip dhcp pool 1 network 10.50.50.0 255.255.255.248 bootfile R9-config option 150 ip 172.16.0.59 default-router 10.50.50.1 Now, according to the following link: http://www.cisco.com/univercd/cc/td/doc/product/software/ios123/123cgcr/ipra s_r/ip1_a1g.htm#wp1080218 , the "bootfile" command is used to specify the name of the default boot image for a Dynamic Host Configuration Protocol (DHCP) client. As far as I am concern, the "boot image" and "configuration file" are two different things. The question on my book clearly states that the new router will load a configuration file from the TFTP NOT a Boot Image (IOS). Could anybody provide any feedback about this? In my opinion, the "bootfile" command is used to load an IOS image, not a configuration file. Thanks in advance! __________________________________________________ Do You Yahoo!? Tired of spam?
