Introduction

iPXE boot in ASR9K

Migration recommendation document for Cxr to Exr.

https://www.cisco.com/c/en/us/td/docs/routers/asr9000/migration/guide/b-migration-to-ios-xr-64-bit/b...

Pre-requisite:

Needed only IOS XR 64-bit ISO image.

Example : “asr9k-mini-x64-6.2.3.iso”

Caveat :

Config will be lost we needed to save the configuration in advance before migration on external server.

This can be done only on a RSP880 , RP2 and above .

Disk and hard disk would be formatted while migration we needed to save the configuration and relevant logs externally .

When IPXE Boot could be done :

During migration from C-xr to E-xr (only using migration script )
Password recovery
When router boot up fails with E-xr .
During Downgrade from 6225 and below we needed to do Ipxe boot

IPXE Boot :

iPXE is a pre-boot execution environment that is embedded in the router and works at the BIOS level. iPXE is used to re-image the system, boot the router in case of boot failure or in the absence of a valid bootable partition.

Summary of Steps:

Before your use the iPXE boot, ensure that config backup is taken in advance to a tftp/ftp path to load the config back after the ipxe boot .
Login to the System Admin console using the admin command.
If router is unable to boot then intiate an OIR of both RP (Active and Standby RP)
After aborting the boot process. you get the following options to boot as mentioned below and choose the option 4 for IPXE boot
After option 4 is selected please press CTRL+b as soon as you see this syslog on the router “Selected external PXE “to enter to IPXE prompt <IPXE>
Manually update IPXE Rommon details before booting via FTP/TFTP:
ENTER THE NEW PASSWORD as prompted
Standby RP will Sync with active RP once active RP is booted successfully .
If standby RP is not getting sync then press ctrl +C and select option 5 from boot.

Steps in details

Step 1: Before your use the iPXE boot, ensure that config backup is taken in advance to a tftp/ftp path to load the config back after the ipxe boot .

Step 2: Login to the System Admin console using the admin command.

The following example shows the output of the command:

sysadmin-vm:0_RSP0# hw-module location all reload

Tue Mar 6 08:12:47.605 UTC

Reload hardware module ? [no,yes] yes

result Card graceful reload request on all acknowledged.

sysadmin-vm:0_RSP0#

Step 3 : If router is unable to boot then intiate an OIR of both RP (Active and Standby RP)

Press Ctrl +C as soon as you see this below log -

Step 6 : Manually update IPXE Rommon details before booting via FTP/TFTP:

Set below variables in iPXE prompt if Rommon variables are not set.

Note: where net0 represents mgmt port0 and net1 represents mgmt port1 :

now open the connected mgmt port (0/1) with this Command “ifopen net0/1 “ then boot the require image from tftp location or reachability.

And next open the front ports and execute the boot command in ipXE prompt

iPXE>ifclose net0

iPXE>ifopen net 1

iPXE>boot tftp://YOURSERVER_IP/file path/image.iso

I am planning to clean install using front panel USB media.

Is the USB media format FAT32?
Should I save the eXR ISO Image in the Root directory of the USB media?
Can I select images to boot from multiple ISO files in the USB media? (Does it fail if there are multiple files?)

IPXE IPV6 boot is supported?

Can you please share the procedure?

Since you don't have any ROMMON variables configured, You need to select option 1 first (32 bit Classic), break & enter ROMMON, configure ROMMON IP/Mask etc, then reboot to the 64-bit boot menu again & then select Option 4. From there you can hit CTRL-B and enter iPXE.
