Adding to Heasley’s comments here. You can transfer via SSH based methods and
increase speeds using this command as of IOS XR 7.1.x+

Sander,
How big? How slow?
You can reply to me off or on list.
About 8 to 10 years ago, we had a large effort to improve this.
Now customers push many megabytes of prefix-sets several times a day and it
works.
I have sent some questions internally to get a better answer.

I agree, I don't think you can get around the XR config bottleneck. But
that's not really the end of the story.
Let's think about why the loading time matters to Sander (Sander, please
chime in here):
1. They have to address an immediate issue for a customer (internal or
external) and the custome

Pushing thousands of lines via CLI/expect automation is def not a great
idea, no. Putting everything into a file, copying that to the device, and
loading from there is generally best regardless. The slowness you refer to
is almost certainly just because of how XR handles config application. If

Hi Saku.
I don't know that Netconf or gRPC are any faster than loading cli. Those
protocols facilitate automation so that the time it takes to load any one
device is not a significant factor, especially when you can roll out
changes to devices in parallel. Also, it's easier to build the changes in
Can Andrian and Joshua explain what they specifically mean, and how
they expect it to perform over what Steffann is already doing (e.g.
load https://nms/cfg/router.txt)? How much faster will it be, and why?
Can Steffan explain how large a file they are copying, over what
protocol, how long does it
Two options:
- gRPC
- Netconf
You can use tools like paramiko,netmiko or napalm that are widely used
to programmatically configure and manage your XR router.

Netconf is really nice for atomic changes to network devices, though it
would still take some time for the device to process such a large change.

Hi,
What is the best/most efficient/most convenient way to push large prefix lists
or sets to an XR router for BGP prefix filtering? Pushing thousands of lines
through the CLI seems foolish, I tried using the load command but it seems
horribly slow. What am I missing? :)
Cheers!
