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.
1. 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 three minutes, regardless of whether a cable is connected.
2. A BootP server responds to the BayStack router’s request with the directory
path names (F
igure 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.
3. The BayStack router stops sending BootP requests.
