CAUTION:
Warning: Before performing this procedure, make sure that you can successfully boot
from the network using the manual boot procedure option 3 or 4. Refer to the section
Option 3: Boot from Network on page 4-37.
Step 1 Copy the router software file KERNEL.F2K (or KERNEL.FPL for an IDSL router) to a
directory where it can be accessed by a TFTP server. The TFTP server must be on
the same LAN as the target router; i.e., there must not be a router or gateway
between the target system and the TFTP server. If the TFTP sever is not on the
same network as the target router, enter the gateway from the boot menu as
described in the previous section.
Step 2 Log into the Command Line Interface.
Step 3 Enter the reboot command to synchronize the file system and reboot the router.
Because the kernel is no longer stored in flash memory, the router tries to boot from
the network. If you have never set permanent boot parameters, the router attempts
to locate a BOOTP or RARP server. If the router successfully reboots from the
server, go to step 7.
Step 4 Select option 4 to boot router software from the TFTP server using temporary
network boot parameters. You are prompted for:
the routers boot LAN IP address,
the TFTP servers IP address,
the load address, and
the filename of the routers kernel saved on the server.
Step 5 Note that the LAN IP address is the proper address to use during the network boot
and this may differ from the IP address ultimately assigned to the router. Enter the
temporary network boot parameters (hit the return key for the load address). If all
entered information is valid, the router boots from the network. An example follows:
Enter selection: 4
Enter my IP address:
128.1.210.65
Enter server IP address:
128.1.210.70
Enter load address [80100]:
Enter file name: kernel.f2k
Alternatively, select option 5 to set permanent network boot parameters and then boot
from the network using option 3. You would use this option if you wish to boot from the
network for a period of time before copying the software to flash memory.
Step 6 After the boot is complete, verify that the kernel is running successfully.
