Obtaining the Kernel and Configuration Files

With a known IP address, the BayStack router can obtain its operating-system

kernel and configuration files over the network. The procedure is the same for

EZ-Install, Netboot, and Directed Netboot.

The BayStack router sends a BootP request for the path names of the startup

files.

The BayStack router issues the request simultaneously through all serial

(COM), Ethernet, and token ring (ARN only) interfaces that have IP

addresses. The BayStack router issues this request periodically for

approximately 3 minutes, regardless of whether a cable is connected.

A BootP server responds to the BayStack router’s request with the directory

path names (Figure 1-3)

Figure 1-3. Obtaining the Path Names of the Kernel and Configuration Files

The first router interface that processes the BootP response acts as the TFTP

client in the remaining steps.

The BayStack router stops sending BootP requests.
