What is Boot CONFIG?

Router nonvolatile con®guration database memory contains the data that controls the router boot and dump capabilities. The Boot CONFIG commands allow you to modify this data.

Using Boot CONFIG commands, you can:

vAdd, modify, or remove entries from the boot and dump con®guration database.

vDisable or enable network memory dumping and assign a unique name to the dump ®les.

vUse the TFTP protocol to transfer (using the TFTP command or copy command) con®guration information between router memory and remote hosts.

vView the current boot and dump con®guration database.

vStore ®le images to the Integrated Boot Device (IBD).

vStore the current image to the IBD.

vLeave the Boot CONFIG command environment and return to the CONFIG process.

vList the contents of the IBD.

vDelete ®les from the IBD.

vCopy ®les to and from the local router memory and another local router memory or host ®le system.

vSave any changes you have made to system and protocol parameters.

Changes made to system and protocol parameters through Boot CONFIG take effect when you restart the router or when you reload the router software.

Con®guring Booting

Boot ®les are the same as load image ®les. A boot ®le contains the software load for the router and resides on a host server, or an IBD. The host server is, for example, any PC, router, or workstation, that is running the IP protocol and TFTP. The boot con®guration database can contain an entry for each boot ®le, con®gured using the add command. Each entry contains the address of the host server, the next hop router, and the timeout, path, and ®lenames of the boot ®les.
