RFC 951: Bootstrap Protocol (BOOTP)

RFC 1533: DHCP Options and BOOTP Vendor Extensions

RFC 1542: Clarification and Extensions for the Bootstrap Protocol (updates 951)

A BOOTP request is broadcast through the Ethernet port to the local network. The request is not sent from the ADSL port because the boot sector does not contain the code necessary to transmit over the WAN link. If a BOOTP server is on the local network and is configured correctly, it returns a BOOTP response. Once the Megabit Modem CRA-C receives a BOOTP response, it keeps the IP address, boot server, default router, and any other information associated with the module in the configuration sector of the flash. Subsequent BOOTP responses for the Megabit Modem CRA-C are ignored.

When a BOOTP server is not on the local network, the request fails unless there is a BOOTP agent on the network that recognizes and forwards the request to the server. The BOOTP server does not contain an entry that corresponds to the MAC address of the Megabit Modem CRA-C.

From the console interface, you can configure network parameters and save them to flash so the BOOTP operation can be bypassed. The BOOTP server should be connected to the same segment as the Megabit Modem 10BASE-T port.
