Selecting a Boot Configuration

1-9

The upstream router sends the IP address and subnet mask to the

booting router in a BOOTP response message.

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

interface that receives a BOOTP response.

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

router, in RAM.

Getting the Software Image and Configuration Files

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

files as follows:

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.
