Selecting a Boot Configuration

6. The upstream router sends the IP address and subnet mask to the booting

router in a BOOTP response message.

7. The ASN assigns the IP address and subnet mask to any synchronous

interface that receives a BOOTP response.

8. The ASN stores these addresses, along with the address of the next-hop router,

in RAM.

Getting the Software Image and Conﬁguration Files

After its gets the IP address, the ASN obtains its software image and conﬁguration

ﬁles as follows:

1. The ASN sends a BOOTP request for the pathnames of a conﬁguration ﬁle

and software image ﬁle.

The ASN issues this request simultaneously through all synchronous and

Ethernet interfaces that have IP addresses. It issues this request periodically

through these ports for about 3 minutes, regardless of whether a cable is

connected.

2. A BOOTP server responds to the router’s request with the directory

pathnames; the ASN stops sending BOOTP requests for the pathnames

(Figure 1-3).

The ﬁrst ASN interface that processes the BOOTP response acts as the TFTP

client in the remaining steps.
