Is this specific to vmhost device or any Junos device?

I have only tested it on vmhost devices. I don't remember anything in the
underlying code that was specific to vmhost. I would expect this behavior
on any junos device.

Hi @jnicholson56
Thanks ,
I have tested with Dual RE MX device with connection: local
From the logs it looks to be image downloaded to RE0 , RE0 is installed first and then package is pushed to RE1 , RE1 installation happens .

I have not yet tested the installation on vmhost device, I will check it and update the logs here .

Hi @jnicholson56
Thanks ,
When we set the parameter all_re: True in the playbook
We are sending the following RPC to RE0 of the device, as part of the RPC execution, image gets downloaded to the RE0 and installation continues.
<request-package-add><no-validate/><package-name>http://x,x,x,x//junos-x86-64-21.4R3-S2.3.tgz</package-name><re0/></request-package-add>
After successful completion of the above RPC, another request-package-add RPC for RE1 is executed, as part of the RPC execution, image gets downloaded to the RE0 and pushed to the RE1 for installation,
<request-package-add><no-validate/><package-name>http://x.x.x.x//junos-x86-64-21.4R3-S2.3.tgz</package-name><re1/></request-package-add>
It is as per the implementation of the RPC / command executed on the device, which downloads the package to the local RE from remote URL before installation.
Thanks & Regards

Right. that was the behavior I also observed. My ask was can it be changed?
The first test you did is a bit confusing. I think what is happening is that when you tell it to install to RE1, it is downloading the file to RE0 (primary) and then pushing it to RE1. It looks like it is still downloading twice as opposed to once. Each RE has the download from 10.220.22.5 portion which to me says it is downloading from that ftp server.

I have observed that you can watch /var/home/remote/ on the primary RE and you will see a tmp folder with a random name will be added for each download.

Hi @jnicholson56
Thanks for the information.
I will explore the supported "request system software add /request-package-add" command options and update .

After going through the documentation of "request system software add" JUNOS CLI command, this is the default behavior of JUNOS CLI/RPC command to download the package to the RE0 and install the package.
JUNOS CLI/RPC command does not provide the option to install the both the REs with single download.
We rely on the underlying JUNOS CLI/RPC commands to perform the ansible tasks and JUNOS CLI command does not provide any such options and this is the limitation of JUNOS CLI/RPC command.
request system software add http://x.x.x.x//junos-x86-64-21.4R3-S2.3.tgz ?
Possible completions:
<[Enter]> Execute this command
best-effort-load Load succeeds if at least one statement is valid
delay-restart Don't restart processes
force Force addition of package (ignore warnings)
no-copy Don't save copies of package files
no-validate Don't check compatibility with current configuration
on-primary Install image on primary partition while booted on secondary partition
re0 Install package on RE0
re1 Install package on RE1
reboot Reboot system after adding package
unlink Remove the package after successful installation
+ upgrade-with-config Additional configs ('text/xml' format) to be applied on upgrade
validate Check compatibility with current configuration
validate-on-host Remote host or user@host for configuration validation
validate-on-routing-engine Routing engine for configuration validation
| Pipe through a command
If we don't specify the RE0/RE1 , then by default it downloads the image to the current RE and install the packages
request system software add http://x.x.x.x//junos-x86-64-21.4R3-S2.3.tgz
when we specify RE0, then it downloads the image to the RE0 and proceeds with installation .
when we specify RE1, then it downloads the image to the RE0 and pushes the image to RE1 and proceeds with installation
we can try ISSU option for Dual RE devices , since it is the same JUNOS CLI/RPC command with option "in-service-upgrade" might download the images again to both the REs .
Please proceed with JUNOS PR for single package download option needs to be supported .
